Abstract: Aim

ing at the chattering phenomenon of permanent magnet synchronous motor (PMSM) when the load was abrupt, a repetitive synovial control method was proposed. Firstly, the article introduced the mathematical model of permanent magnet synchronous motor and the basic principle of synovial variable structure in detail, and a synovial control strategy was applied to replace the traditional PI control in speed loop of PMSM. Secondly, the basic principle of repetitive control was comprehensively analyzed. On the basis of synovial control, repetitive control was added to the control system. And proposed a new type of repetitive synovial control approach, a motor simulation model based on MATLAB/Simulink was established. The simulation result shows that the scheme has better system responsiveness in the rising stage of motor speed; when the motor load is abrupt, the maximum mutation value of motor speed is reduced by 74.55% compared with the use of the synovial control, and the time of motor returns to the stable state also becomes 37.5% of the original; it is verified that the presented repetitive synovial control algorithm has strong load resistance and system stability.

Key words: Permanent Magnet Synchronous Motor (PMSM), synovial control, repetitive control, motor simulation model, repetitive synovial control, load resistance
