| 摘 要： | 从永磁同步电机的数学模型出发,设计滑模自适应观测器,将电流误差作为滑模开关函数,根据李亚普诺夫稳定性理论来判定观测器的收敛性的条件,并根据滑模观测器求解出扩展反电动势,将反电动势和位置误差构成锁相环,通过锁相环得到准确的位置和转速信息,最后通过仿真结果验证了所提方案的可行性.

| Abstract: | The slid motor observer was created based on the mathematical model of permanent magnet synchronous motor.The current error was defined as the slid sign function,and the stability of the observer was guaranteed by the Lyapunov stability theory.By the backemf obtained from slid motor observer and position error,PLL(Phase-Locked Loop) was structured,with which position and speed was calculated.Simulink result indicated the valid of the theory. |
