| 摘 要： | 针对永磁同步电机（PMSM）负载转矩已知、未知和定子电阻不确定情况，采用一种新的能量成形和端口受控哈密顿（PCH）系统方法，研究了PMSM的建模与速度控制问题，并建立了PMSM的PCH模型，给出了闭环系统期望的哈密顿函数，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。仿真结果表明，所提出的方案对负载扰动和定子电阻变化具有很强的鲁棒性。

| Abstract: | Applying a novel method of energy shaping and Port-Control Hamiltonian(PCH) systems,the modeling and speed control of permanent magnet synchronous motor(PMSM) are developed when load torque is known and unknown as well as stator resistance is uncertain. A PCH model of PMSM is established. The controller and load torque observer are designed. The equilibrium stability of the system is also verified. The simulation results show that the proposed scheme exhibits good robust performances in presence of stator resistance variations and load disturbances. |
