Active Fault-tolerant Control for Surface Permanent Magnet Synchronous Motor under Demagnetization Fault

This paper introduces a novel method for controlling a surface permanent magnet synchronous motor (SPMSM) during demagnetization
fault conditions. The proposed fault-tolerant control (FTC) system incorporates a combination of a fuzzy extended state observer (FESO)
based on an interval type 2 fuzzy logic controller (IT2FLC) and second-order sliding mode control (SOSMC) utilizing the super-twisting
algorithm. The FESO aims to identify and eliminate demagnetization faults through reconstruction control. The FTC system enhances
the dynamic performance and disturbance rejection of the SPMSM, providing a robust solution in the event of a demagnetization fault.

A New Improved Control for Power Quality Enhancement in Double Fed Induction Generator using Iterative Learning Control

This work presents a new Fault Tolerant Control approach for a doubly fed induction generator using Iterative Learning Control when the fault occurs. The goal of this research is to apply the proposed ILC controller in conjunction with vector control for doubly fed induction generator to enhance its reliability and availability under broken rotor bars. However, the performances of classical VC control are often characterized by their inability to deal with the effects of faults. To overcome these drawbacks, a combination of VC control and iterative learning control is described. The input control signal of the VC controller is gradually regulated by the ILC harmonic compensator in order to eliminate the faults effect. The improvement of this approach related to active and reactive power ripples overshoot and response time have been explained. Which active and reactive power response time have been reduced more than 84% and 87.5 % respectively. The active and reactive power overshoots have been reduced about 45% and 35% respectively. The obtained results emphasize the efficiency and the ability of the proposed FTC to enhance the power quality in faulty condition.

Power Quality Enhancement in Double Fed Induction Generator Using Iterative Learning Control

This paper presents a combination of the proposed Sliding Mode Control and a newly developed iterative learning control technique for
harmonic compensation for the fault’s effect to adjust the active and reactive power to their desired references. The classical SMC cannot deal with
the effect of the faults that can achieve graceful system degradation. Indeed, when there are significant disturbances, the input control signal of the
SM controller is gradually adjusted by the ILC harmonic compensator in order to reject the disruptive harmonics effectively. Simulation results are
given to demonstrate the effectiveness of the suggested SMC-ILC in terms of active and reactive power responses. The obtained results illustrate
that the SMC-ILC strategy is valid and capable of ensuring a ripple-free operation in the presence of faults. The proposed controller is characterized
by its simple design, robustness, and efficiency, which are convincing for practical application and may be used as a solution to the current Fault
Tolerant Control.

Optimization of PI Controller Parameters by GWO Algorithm for Five-Phase Asynchronous Motor

Operation at low speed and high torque can lead to the generation of strong ripples in the speed, which can deteriorate the system. To reduce the speed oscillations when operating a
five-phase asynchronous motor at low speed, in this article, we propose a control method based on Gray Wolf optimization (GWO) algorithms to adjust the parameters of proportional–integral (PI) controllers. Proportional–integral controllers are commonly used in control systems to regulate the speed and current of a motor. The controller parameters, such as the integral gain and proportional gain, can be adjusted to improve the control performance. Specifically, reducing the integral gain can help reduce the oscillations at low speeds. The proportional–integral controller is insensitive to parametric variations; however, when we employ a GWO optimization strategy based on PI controller parameters, and when we choose gains wisely, the system becomes more reliable. The obtained results show that the hybrid control of the five-phase induction motor (IM) offers high performance in the permanent and transient states. In addition, with this proposed strategy controller, disturbances do not affect motor performance.

Fault Tolerant Control of PMSM based on Improved Exponential ESO

In this work, a Fault-Tolerant Control (FTC) design is based on a novel reaching law sliding mode control (SMC) with an improved exponential extended state observer (ESO) for a 3-phase Permanent Magnet Synchronous Motor (PMSM) is proposed. Moreover, a direct field-oriented control based on ESO with a novel reaching law SMC is designed to achieve robust performance against parameter variations and external disturbances. The main goal of using an improved exponential ESO is to detect and reconstruct disturbances and faults. Furthermore, the stability of these observers and controllers is proved by using the Lyapunov stability theory.

Fault-tolerant control of PMSM based on second-order sliding mode

This paper presents a fault-tolerant control (FTC) based on a second-order sliding mode using a super-twisting algorithm applied to a 3-phase permanent magnet synchronous motor (PMSM). First, a second-order sliding mode control (SOSMC) is applied to the direct field-oriented control (FOC), which improves dynamic response and anti-disturbance performance by maintaining the speed and currents within their desired reference values. Second, a second-order sliding mode observer (SOSMO) is constructed in order to estimate and reconstruct the faults. Finally, the effectiveness of the proposed FTC has been verified through simulation using MATLAB/Simulink software.

2019 ICCMAS International Conference On Computational Methods In Applied Sciences

Induction motor (IM) are nowadays widely used in industrial applications specially in electric vehicles (EVs) and traction locomotives, due to their high efficiency high speed and lifetime. However, since EV motor systems are easily influenced by un-certainties parameter variations, external load disturbance and actuator faults, both nonlinear control techniques based faults detection and reconstruction have received considerable attention during the past few decades. This paper proposes an improved actuator fault reconstruction and estimation design for a class of high-performance induction motor (IM) drives that propels to electric-vehicle (EV). In this purpose, a nonlinear controller based backstepping strategy is adopted to deal with tracking problems under external and internal un-certainties.

Dynamic Modeling and Design of interval type-2 fuzzy sliding-mode controller of an Hexacopter UAV

The control of the hexarotor helicopter includes nonlinearities, uncertainties and external perturbations that should be considered in the design of control laws. This paper presents a control strategy for an underactuated six degrees of freedom (6 DOF) hexarotor helicopter, based on the coupling of the interval type-2 fuzzy logic (IT2FL) control and sliding mode control (SMC). The main purpose of this work is to eliminate the chattering phenomenon. To achieve our purpose we have used a IT2FL control to generate the hitting control signal, the results of our simulations indicate that the control performance of the hexacopter are satisfactory and the proposed

Backstepping Fault Tolerant Control for Double Star Induction Machine under Broken Rotor Bars

In this paper a Passive Fault Tolerant Control (PFTC) based on non-linear backstepping control is proposed for a Double Star Induction Machine (DSIM) under Broken Rotor Bars (BRB) fault of a squirrel-cage in order to improve its reliability and availability. The proposed PFTC is able to maintain acceptable performance in the event of BRB. This control technique guarantees robustness against uncertainties and external disturbances and is also able to deal directly with faults by compensating for the effects of the BRB fault in the machine without prior knowledge on the fault, its location and its severity. The stability of the closed-loop is verified by the exploitation of the Lyapunov theory. a comparative study is made between the proposed Fault Tolerance Control (FTC) and Sliding Mode Control (SMC) for demonstrating the performance and effectiveness of the proposed controller. The results obtained show that the proposed FTC has a better robustness against the BRB fault where the DSIM operates with acceptable performance in both speed and torque.

Fault-Tolerant Control Based on Sliding Mode Controller for Double-Star Induction Machine

This paper presents a fault-tolerant control (FTC) strategy for double-star induction machine subject to stator and rotor faults. To steer the speed and the flux to their desired references, a nonlinear sliding mode controller (SMC) is designed. However, the proposed SMC can’t deal with the faults effect which can achieve graceful system degradation. In order to compensate the faults effect, an appropriate combination between the proposed SMC and a new developed fault detection and compensation block is made. Simulation results are presented to show the effectiveness of the proposed FTC in terms of speed and flux responses using an estimator of rotor flux. Compared with SMC, the obtained results confirm the validity of the proposed FTC strategy and its ability to ensure a ripple-free operation when the fault occurs. In this kind of multiphase machines, the proposed controller is applied for the first time; its efficiency, robustness and simple design are promising for practical implementation and can be an alternative to the existing FTC.

Fault tolerant control for modified quadrotor via adaptive type-2 fuzzy backstepping subject to actuator faults

In this paper, a robust attitude and position control of a novel modified quadrotor unmanned aerial vehicles (UAV) which has higher drive capability as well as greater robustness against actuator faults than conventional quad-rotor UAV has been developed. A robust backstepping controller with adaptive interval type-2 fuzzy logic is proposed to control the attitude and position of the modified quadrotor under actuator faults. Besides globally stabilizing the system amid other disturbances, the insensitivity to the model errors and parametric uncertainties are the asset of the backstepping approach. The adaptive interval type-2 fuzzy logic as fault observer can effectively estimate the lumped faults without the knowledge of their bounds for the modified quadrotor UAV. Additionally, the type-2 fuzzy systems are utilized to approximate the local nonlinearities of each subsystem under actuator faults, next and in order to achieve the expected tracking performance, we used Lyapunov theory stability and convergence analysis to online adjust adaptive laws. As a result, the uniformly ultimate stability of the modified quadrotor system is proved. Finally, the performances of the proposed control method are evaluated by simulation and the results demonstrate the effectiveness of the proposed control strategy for the modified quadrotor in vertical flights in presence of actuator faults.

Actuator fault tolerant control using adaptive RBFNN fuzzy sliding mode controller for coaxial octorotor UAV

In this paper, a robust controller for a Six Degrees of Freedom (6 DOF) coaxial octorotor helicopter control is proposed in presence of actuator faults. Radial Base Function Neural Network (RBFNN), Fuzzy Logic Control approach (FLC) and Sliding Mode Control (SMC) technique are used to design a controller, named Fault Tolerant Control (FTC), for each subsystem of the octorotor helicopter. The proposed FTC scheme allows avoiding difficult modeling, attenuating the chattering effect of the SMC, reducing the rules number of the fuzzy controller, and guaranteeing the stability and the robustness of the system. The simulation results show that the proposed FTC can greatly alleviate the chattering effect, good tracking in presence of actuator faults.
