摘要
双三相永磁同步电机因其损耗小、效率高、容错能力强等特点,广泛应用于航空航天技术、电动汽车等领域.为优化双三相永磁同步电机控制性能,采用双d-q坐标变换对双三相永磁同步电机进行数学建模,为减小电流纹波,在传统模型预测电流控制策略基础上,增加延时补偿;考虑电机参数扰动的影响,提出一种能够对参数进行在线估计的滑模观测器,以提高控制系统鲁棒性,最后在MATLAB/Simulink中进行系统抗负载扰动与鲁棒性能仿真分析.仿真结果表明,改进后的控制策略提高了电机的响应速度,超调减小,系统对电机参数扰动的敏感性减弱,系统抗负载能力和鲁棒性增强.
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.
