技术资料 基于滑模观测器与分数阶锁相环的无传感器PMSM矢量控制

Abstract: A sliding mode observer and fractional-order phase-locked loop (FO-PLL) method is proposed for the sensorless speed control of a permanent magnet synchronous motor (PMSM).The saturation function is adopted in order to reduce the chattering phenomenon caused by the sliding mode observer. In ...

技术资料 射频锁相环基础理论

一.基础理论锁相环路(Phase Locked Loop)是一个闭环的相位控制系统,它的输出信号的相位能自动跟踪输入信号相位。系统框图如下:当0,(1)与0:(1)相等时,两矢量以相同的角速度旋转,相对位置,即夹角维持不变,通常数值又较小,这就是环路的锁定状态。从输入信号加到锁相环路的输入端开始,一直到环路达到锁定的全过 ...
