【摘要】 根据永磁同步电动机的非线性动态数学模型,采用直接反馈线性化控制方法,实现了永磁同步电动机系统的输入输出线性化。通过此方法设计的速度跟踪控制,在保证整个闭环系统稳定的情况下,提高速度跟踪的快速性。另外在此基础上,采用了负载转矩扰动观测器,减小了负载扰动对速度的影响。仿真表明,反馈线性化控制设计简单,有很好的速度跟踪性能。更多还原

【Abstract】 Based on nonlinear dynamic mathematical model of PMSM,the PMSM system is inputoutput linearized with the direct feedback linearization method.By this linearization model,the speed tracking control law is designed to increase the celerity of speed tracking while keeping the whole closed loop system stable.The observer of disturbance torque is applied to reduce the affect of torque disturbance on speed.The simulation results show that the proposed method is simple and has good speed tracking performance.更多还原
