针对负载转矩已知和未知情况,本文采用端口受控哈密顿(port-controlled Hamiltonian,PCH)方法,分别研究了双馈感应电机(doubly-fed induction machine,DFIM)哈密顿建模与控制问题,建立了双馈感应电机的PCH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,采用能量成形、阻尼注入和互联配置的方法设计出系统控制器,并且在负载转矩未知时设计负载转矩观测器。通过Matlab/simulink进行仿真验证,仿真结果表明,系统动态响应比较快,具有较好的稳态性能和速度跟踪性能。证明所提出的PCH控制方法是有效的。

State Error Port Hamiltonian Modeling and Control of a Doubly-Fed Induction Machine

The Hamiltonian modeling and control problem of doubly-fed induction machine（DFIM） are studied based on the use of Port-Controlled Hamiltonian（PCH） method in this paper when the load torque is known and unknown respectively. The PCH model of a DFIM is established. The desired closed-loop PCH system structure is given and desired closed-loop Hamiltonian function is selected. The system controller is designed by using energy shaping, damping injection and interconnect assignment, and the load torque observer is designed when the load torque is unknown. The simulation result based on Matlab/simulink shows that the system dynamic response is relatively fast and has good steady state performance and speed tracking performance. It proves that the proposed PCH control method is effective.
