摘　　要：针对负载转矩已知和未知情况,研究了双馈感应电动机(doubly-fed induction machines,DFIM)调速系统的哈密顿系统建模与控制问题.采用端口受控哈密顿(port-controlled Hamiltonian,PCH)方法,建立了DFIM的PCH系统模型,给出了期望的闭环系统PCH结构,选取了期望的闭环哈密顿函数,设计了控制器和负载转矩观测器,分析了平衡点的稳定性,从而实现了DFIM电气子系统与机械子系统的控制.仿真结果表明所提出的控制方法是有效和可行的.Applying a novel method of Port-Controlled Hamiltonian （PCH） systems, the modeling and control of doubly-fed induction machine （DFIM） are presented when load torque is known and unknown, A PCH model of DFIM is established. A doubly-fed induction machine and a controller are interconnected, desired closedloop PCH system structure is obtained by the feedback. The desired closed-loop Hamiltonian function is given. The controller and load torque observer are designed. The equilibrium stability of the system is also verified. The control of electrical subsystem and mechanical subsystem are implemented. The simulation results show that the propesed scheme has a good performance and practical use prospects.
