混合磁路电机的哈密顿建模与控制

Modeling and control of hybrid excitation synchronous motors based on hamilton system theory

针对电机传统控制策略对参数变化敏感等问题,从能量的观点出发,将哈密顿能量系统理论应用于混合磁路电机,将混合磁路电机数学模型表示成了广义耗散哈密顿系统的形式,给出了混合磁路电机的哈密顿能量函数,设计了混合磁路电机的非线性稳定控制器和负载观测器。仿真结果验证了理论分析的正确性和控制律的有效性。

Aimed at a serious problem in traditional control strategy sensitive to changes of parameters, the application of Hamilton energy system to hybrid excitation synchronous motors （HESM） is studied from energy viewpoint. Mathematic model of HESM is presented was generalized dissipative Hamiltonian system. Hamilton energy function of HESM was also presented. Nonlinear stability controller and load observer for HESM were designed. Simulations verify the effectiveness of the controller and the observer.
