ADRC Based Sliding Mode Control for PMSM Within High-Voltage Circuit Breaker
摘要
This paper addresses control technology of permanent magnet synchronous motor (PMSM) which is employed to drive the high-voltage circuit breaker. In order to improve the current controllers’ tracking performance of PMSM with parameter uncertainties, an active disturbance rejection control (ADRC)-based sliding mode control (SMC) strategy is proposed. In the proposed control method, SMCs are developed taken account of the boundary of the uncertainties, and extended state observers (ESOs) in parallel are designed to estimate the uncertainties in the PMSM model. Compared with the SMC method, the value control parameters of ADRC-SMC method are bettered by using ESO. The simulation results show that the proposed ADRC-SMC method can improve dynamic tracking and minimize the chattering of PMSM system.
