Robust Model Prediction Control Study of Dual Three-phase Permanent Magnet Synchronous Motor Based on Parameter Perturbation Estimation
摘要
Abstract
Dual three-phase permanent magnet synchronous motors are widely used in such fields as aerospace technology and electric vehicles,etc.because of their low losses,high efficiency and strong fault tolerance,etc.To optimize the control performance of the dual three-phase permanent magnet syn-chronous motor,the dual d-q coordinate transformation is used to mathematically model the dual three-phase permanent magnet synchronous motor,and to reduce the current ripple,delay compensation is added on the basis of the traditional model prediction current control strategy.The effect of perturbation of motor parameters are considered,a sliding mode observer with on-line estimation of parameters is proposed to improve the robustness of the control system.Finally,the system is simulated and analyzed in MATLAB/Simulink for its anti-load perturbation and robustness.The simulation results show that the improved con-trol strategy improves the response speed of the motor,reduces overshoot,reduces the sensitivity of the sys-tem to motor parameter perturbations,and enhances the load resistance and robustness of the system.关键词
