Abstract

In this paper, a PMSM vector control algorithm based on non-singular terminal sliding mode observer was designed. Based on the traditional sliding mode observer, the second-order sliding mode surface is established and the speed was estimated by using phase-locked loop method. Compared with the traditional sliding mode observer, the non-singular terminal sliding mode can effectively filter the high-frequency harmonics of the system without using a first-order low-pass filter, so the chattering suppression effect of the observer was more remarkable. The simulation model was built in the simulation environment of MATLAB/Simulink, and its simulation results prove the rationality, feasibility and effectiveness of the design of system.
