A Sliding Mode Observer Design Method for Induction Motor Control System

摘要：

This paper proposes an observer based on the nonsingular terminal sliding mode (NTSM) method and the high-order sliding mode (HOSM) method for estimating the rotor speed and the rotor flux in the induction motor control system. A terminal sliding mode observer is designed to estimate the rotor speed and the rotor flux of the motor system with fast convergence and better tracking precision. A high-order sliding mode control law is utilized to guarantee the stability of the observer and eliminate the chattering. The simulation results show that the proposed method can converge to actual value quickly with high precision.
