摘要
采用哈密顿系统理论对异步电动机进行建模与速度控制。应用端口受控哈密顿系统理论,建立了异步电动机的非线性PCH数学模型及仿真模型,设计了系统的控制器和负载转矩观测器,分析了系统平衡点的稳定性。在Matlab/Simulink中,搭建异步电动机哈密顿控制系统的仿真模型。仿真结果表明,所提出的方案对负载扰动具有很强的鲁棒性。
A novel method based on the theory of Hamiltonian systems for the modeling and speed control of induction motor (IM) is presented in this paper. A nonlinear mathematical model of IM is established in theory of port-controlled Hamiltonian systems. The controller and load torque observer are designed. The equilibrium stability of the system is also verified. In Matlab/Simulink, the model of IM's Hamiltonian control system is established. The simulation results show that the proposed scheme exhibits good robust performances in presence of load disturbances.
