Abstract
In permanent magnet synchronous motor(PMSM)control system, there are motor parameter disturbances. In order to improve the performance of deadbeat predictive current control (DPCC), the motor parameter disturbances are need to be compensated. In this paper, firstly a mathematical model of PMSM was used to analyze the influence of parameter disturbance on DPCC. And then, an autoregression model was designed for the estimation of stator resistance disturbance and stator inductance disturbance, using the disturbances of the previous several control periods to estimate the parameter disturbance of current control period. Finally, the estimated parameter disturbances were compensated to the input of DPCC to control the PMSM. Simulation and experimental results show that the proposed method can effectively suppress the disturbance of PMSM stator resistance and stator inductance.
