Research on PMSM Control for Position Sensorless Based on Sliding Mode Observer
摘要
Abstract
In the permanent magnet synchronous motor (PMSM) control strategies for position sensorless, the rotor position estimation through voltage and current based on observer is an effective scheme contrasting to conventional control strategies using position sensor, which has dead-zone at standstill and low speed. A new control strategy that other-control and self-controlled are combined with was presented, the method of other-control is adopted at standstill and low speed, the PMSM is running with constant volts/hertz (V//) control and switches over to self-controlled when the sliding mode observer(SMO) can observe the rotor position to realize the space vector pulse width modulation. Studies show that this approach can solve the dead-zone at standstill and low speed , which suits to the PMSM of fans and pumps that have low performance at standstill and low speed.关键词
