Sensorless Control of AC Servo Motor Based on Sliding Mode Observer
摘要
Abstract
A sensorless control method of permanent magnet synchronous AC servo motor based on sliding mode observer ( SMO) was presented. Through the analysis for mathematical model of PMSM in static coordinate system, extended electromotive force ( EEMF) estimation which contains traditional back EMF and a kind of voltage related to the saliency of the motor was introduced based on the sliding mode current observer, the sliding mode observer was constructed to estimate the EEMF component in two-phase static coordinate system. Analyzed the reasons of the existence of chattering, Sigmoid function was used to reduce the chattering, instead of constant switching function. Using extended Luenberger observer to observe the position and velocity of the rotor. Simulation results were provided to verify its feasibility and effectiveness.关键词
