Abstract

A Sliding Mode Controller of Permanent Magnet Synchronous Motor (PMSM) is analyzed and designed in this paper. Because of non-linearity, strong couple and disturb sensitivity of PMSM, it is difficult for linear control technology to get perfect control performance of PMSM. Sliding Mode Control (SMC) is an efficient robust control method, which can self-adjust controller structure online, and is non-sensitive to parameter variety and outside disturb. dq Coordinate based rotor reference model of PMSM is built up. Principles and characters of SMC are analyzed in theory. Model and design of SMC of PMSM are deduced in details. Finally, simulation model is built up and various simulations are carried out under MATLAB/Simulink. Simulation results show that SMC is more robust than PI.

Conclusions

In this paper, model of PMSM in dq coordinate rotor reference and fundamentals of SMC are analyzed. SMC control system of PMSM is deduced in details and built up Simulation results indicate that SMC has better steady performance than PI. For load variation when motor running, SMC has very strong robustness, and can enter into steady state in short time, which makes it fit for operating mode of load variation frequently.
