【摘要】 针对隐极式永磁同步电动机,采用端口受控哈密顿模型(PCH)来对电机模型进行研究,并采用互联阻尼分配方法结合PCH电机模型设计电机在负载转矩已知时的控制器和负载转矩未知时的控制器及转矩观测器,为非线性永磁同步电机控制系统提供一个很好的解决方案。仿真实验结果表明:该解决方案所需要参数少且意义明确,容易调节;系统能快速达到渐近稳定,响应时间短且响应平滑无超调;动态性能好,对负载的变化具有很强的适应性和扰动抑制能力。更多还原

【Abstract】 A high performance speed controller for a surface permanent magnet synchronous motor(PMSM) drive was designed.First,the motor model was studied by port controlled Hamiltonian(PCH) model.Then,the interconnection and damping assignment(IDA) approach with the PCH motor model was used to design the controller while the load torque is known,and the controller and the torque observer was designed while load torque is unknown.This provides a good solution for the nonlinear PMSM control system.Through the simulation experiment,the solution needs fewer parameters and the meaning is clear and easy to adjust,the system can quickly reach asymptotically stability.The response time is short and the response process is smooth without overshoot.The system has good dynamic performance, and has a strong adaptation and disturbance rejection to the changes of load.更多还原
