Aptive integral sliding mode control for permanent magnet synchronous motor speed regulation system

Abstract

This thesis studies the control problem of permanent magnet synchronous motor (PMSM) by using the integral terminal sliding mode control and adaptive control. Firstly, a novel integral terminal sliding manifold with adaptive control gains is presented and a continuous reaching law is introduced. Secondly, on basis of the integral terminal sliding mode control, two robust control strategies are proposed for the situations of known and unknown disturbances. Finally, a rigorous proof is given for the stability designed controllers by using Lyapunov theory and simulation results are conducted to illustrate the performance of the proposed control strategies.
