摘要
根据永磁同步电动机的数学模型,研究如何运用串级PD控制器来控制混沌。首先在理论上运用劳斯(Routh)判据分析永磁同步电动机模型串级PD控制混沌的可行性,然后通过在平衡点处线性化的雅克比(Jacobian)矩阵来求取PD参数的值。最后在MATLAB/Simulink仿真平台上利用数值仿真实验验证其有效性。通过研究可知,运用串级PD控制可以较好地消除混沌使系统达到一个稳定的状态。该方法具有一定的参考实用性,为永磁同步电动机混沌运动分析或控制打下了研究基础。
According to the mathematical model of PMSM, how to use the cascade PD to control the chaos was studied. Routh criterion was used to analyze the feasibility of permanent magnet synchronous motor model cascade PD controlling chaotic in theory. The value of the PD parameter can be obtained by solving the Jacobian matrix linearized on the banlance point. The validity was verified through the numerical simulation in MATLAB/Simulink. The research showed that cascade PD control was a better system which can eliminate chaos and bring the system up to stable state. This method had a certain reference utility, and the research foundation was laid for the analysis or control of permanent magnet synchronous motor chaotic motion.
