摘要
为了对永磁同步电机进行简单有效的控制,研究端口受控哈密顿系统(PCH)原理在PMSM控制中的应用。推导了标准PCH系统的静态反馈镇定律和系统吸引域,并将PMSM数学模型成功转换为PCH形式,进而根据期望的平衡点和阻耗大小设计了PMSM的PCH控制器。该方法未进行线性化处理,充分利用了系统的端口结构和内部无源性,所设计的控制器物理意义明确,具有参数调节容易、控制器简单的优点,同时无积分饱和的问题,易于工程实现。仿真证明了理论分析的正确性和控制律的有效性。
To the implement of a simple and effective control of the permanent magnet synchronous motor（ PMSM）, application of port- controlled-Hamihonian（PCH） principle to PMSM controll is investigated. The static feedback stabilization law and the according attract range of standard PCH systems are derived. The dynamic model of PMSM is transferred to standard PCH system and a PCH controller is designed with desired stable status and damping. The proposed method avoids linearization while gets full use of port structure and in- ner passivity of the system. The PCH controller with clear physic meanings is easy to tuning, simple to implement and has no integral saturation. Simulation result shows the correctness of theoretic analysis and the effectiveness of the feedback law.
