Research on robust control method of permanent magnet synchronous motor

Abstract During the operation of permanent magnet synchronous motor, traditional vector control method does not match regulator parameters with actual due to disturbance factors such as motor parameter perturbation and load change, resulting in decline performance. The research object robust is uncertain system, which has natural advantages for improving robustness system. Firstly, this paper introduces basic principle implementation process control, simulates analyzes influence on performance, investigates summarizes improvement methods points out disadvantages each scheme; Secondly, similarities differences improved are analyzed compared; Finally, development trend technology based prospected.
