摘要
Abstract
High starting torque of permanent magnet synchronous motors(PMSM)based on sensorless control is a technical challenge.The failure to start motor with high torque may result in thermal damage of frequency converter.This paper proposes a sensorless control strategy for high dynamic response with high starting torque to address the issue in this paper.Firstly,a rotor position observer is designed based on motor current model to improve operation performance of sensorless control at low speed;a stator position observer is designed based on motor voltage model to improve operation performance of sensorless control at medium-high speed.Secondly,a self-adaptive controller by using SMC regulator is constructed to achieve smooth and seamless switching between low and high speed.Finally,simulation result confirms the effectiveness of the proposed strategy and test result confirms a certain degree of robustness against changes in motor parameters.关键词
