【摘要】 应用新的端口受控哈密顿(PCH)系统方法,研究了永磁同步电机(PMSM)的建模与速度控制问题。首先,建立了PMSM的PCH系统模型。然后,利用PCH系统的能量成形和反馈镇定原理,给出了闭环系统期望的哈密顿函数,配置了互联和阻尼矩阵,设计了控制器,并分析了平衡点的稳定性。最后,针对负载未知情形,设计了负载转矩观测器。仿真结果表明所设计的控制器具有很好的性能和应用前景。更多还原

【Abstract】 Applying a novel method of Port-Controlled Hamiltonian (PCH) systems,the modeling and speed control of permanent magnet synchronous motor (PMSM) is developed.First, a PCH model of PMSM is established. Then, using the energy shaping and feedback stabilization theory of PCH system, the desired Hamiltonian function of closed-loop system is given. The interconnection and damping matrix are assigned, and the controller is designed. The equilibrium stability of the system is also analyzed.Finally, the load torque observer is presented when the load torque is unknown.The simulation results show that the proposed scheme has a good performance and practical use prospects.更多还原
