Improved sliding mode observer PMSM speed sensorless control based on two-stage filter

Aimed at the problem of position estimation error and buffeting caused by sliding mode observer in permanent magnet synchronous motor (PMSM) servo system, an improved two-stage filter sliding mode observer was proposed. Firstly, according to the mathematical model of PMSM, the estimation algorithm o...
