摘要: 针对多变量、强非线性、高耦合的永磁同步电机(permanent magnet synchronous motor,PMSM),设计了不依赖精确数学模型的支持向量机(support vector machines,SVM)辨识逆系统,应用多变量非线性控制逆系统理论,对PMSM进行动态解耦控制研究;针对直接逆开环控制鲁棒性差及支持向量机建模误差,设计了基于云模型规则推理的参数自整定PID(Proportional Integral Differential)闭环控制器,提高了系统的鲁棒性。仿真结果表明基于SVM逆系统的云模型整定PID控制策略不依赖被控对象数学模型,系统抗干扰能力较强,在实现定子电流励磁分量和转子转速动态解耦的同时转速能够精确跟踪给定响应,系统具有良好的动、静态特性。

Abstract: Aiming at the problem of multivariable, nonlinearity and strong coupling of the permanent magnet synchronous motor(PMSM), a strategy of inverse system identification which is independent of precise mathematical model and parameters based on support vector machines(SVM) is proposed. The dynamic decoupling control of PMSM is researched based on multivariable nonlinear control inverse system theory. To deal with direct inverse control open-loop system with poor robustness and inverse modeling error of SVM, a parameter self-tuning PID(Proportional Integral Differential) closed-loop controller based on cloud model rule inference is designed. The simulation results confirm that the cloud model PID control based on SVM inverse system incorporates the merits of model-free learning, strong anti-interference capability. While realizing the dynamic decoupling of the excitation component of stator current and rotor speed, the system has high-precision speed tracking feature and excellent dynamic and static performance.
