| 摘 要： | 针对传统全阶滑模观测器存在抖振及观测精度差的问题,提出一种改进全阶滑模观测器的内置式永磁同步电机无位置传感器控制策略.该策略采用准符号函数代替非线性符号函数作为切换函数,并且利用Lyapunov函数和等效控制的思想对系统进行稳定性分析;在此基础上,为了避免电机转速大小变化影响转子位置的估计精度,设计了与电机转速相关的自...

| Abstract: | Aiming at the problems of chattering and poor observation accuracy of traditional full order sliding mode observer(FSMO),a sensorless control strategy of interior permanent magnet synchronous motor(IPMSM)based on improved full order sliding mode observer was proposed.In this strategy,the quasi-sign function was used instead of the nonlinear sign function as the switching function,and the stability of the system was analyzed by using the idea of equivalent control and Lyapunov function.On this basis,to avoid the influence of the motor speed on the estimation accuracy of the rotor position,an adaptive sliding mode gain related to the motor speed was designed.Finally,the correctness and effectiveness of the proposed sensorless control strategy were verified on the 2 kWIPMSM vector control experimental platform. |
