五相永磁同步电动机无模型预测容错控制
Model-free predictive fault-tolerant control of five-phase PMSM
摘要
Abstract
To solve the performance degradation of model predictive current control caused by parameter mismatch in five-phase permanent magnet synchronous motor(PMSM)under open-circuit fault,the novel model-free predictive fault-tolerant control strategy was proposed.The five-phase PMSM model was built in the rotary synchronous frame under open-circuit fault condition,and the total disturbance caused by parameter uncertainties and unmodeled dynamics was analyzed.Based on the ultra-local model,the extended state observer was designed to estimate the disturbance in the fundamental and the third harmonic subspaces.The disturbance was employed as compensation of the voltage references which were obtained on the basis of deadbeat control.The proposed MPFTC model for five-phase PMSM was built in MATLAB/Simulink,and the performance comparison simulation analysis with the traditional MPFTC was conducted.The five-phase PMSM experimental platform was established,and the relevant experiments were carried out by the traditional MPFTC strategy and the proposed MF-PFTC strategy,respectively.The results show that by the proposed method,excellent steady-state,dynamic and robust performance are achieved under both healthy and open-circuit fault conditions,and the proposed strategy is verified.关键词
