Robust RST controller design for induction motor drive for electric vehicle application

This paper presents a new robust control system for induction motor intended for electric vehicle applications (EVA). A new RST controller is designed to accelerate the speed time response without overshoots and to remove the effects of disturbance related to speed sensors. This controller can quickly compensate the load torque disturbance. In order to reduce the measured noise generated by the speed sensor, we proposed an alternative structure based on two control loops. For high-dynamic performance of the control system, we used the indirect stator-flux-oriented control (ISFOC) and the space vector pulse width modulation (SVPWM) techniques. The simulation results show the performance of the proposed solution.
