Abstract
This paper presents an accurate and high-efficiency backstepping fault-tolerant control (FTC) for double star induction machine (DSIM) of 4,5 kw operating with two current sensor faults (CSFs). The DSIM is fed by two cascaded hybrid seven level inverter using pulse width modulation (PWM) control strategies. This passive FTC is based on Lyapunov stability theory and using an estimator of rotor flux. A comparative analysis via Matlab/Simulink is made between the proposed FTC and sliding mode control (SMC) in order to compare the performances of the system using these two control methods. Simulation results prove that the backstepping FTC has a fast dynamic, better tracking performance and better robustness against the CSFs.
