摘要

本文比较了两种观测器同时估计异步电动机转子磁链的速度、位置和相量模量。所分析的观测器是:扩展Gopinath观测器(EGO)和由降阶Gopinath观测器和Peng速度观测器组成的集合。这两种观测器都用于直接转子磁链定向的无传感器矢量控制系统。采用Matlab-Simulink进行数值模拟，实现了对比试验。

Comparative Study Between Extended Gopinath Observer and Back EMF-MRAS Speed Observer Coupled with Gopinath Rotor Flux Observer for Sensorless Vector Control of Induction Motor Drives

The article presents a comparison a two observers used in the simultaneous estimation of the speed, position and phasor modulus of the rotor flux of an induction motor. The analysed observers are: extended Gopinath observer (EGO) and assembly consisting of the reduced order Gopinath observer and the Peng speed observer. Both observers are used in sensorless vector control systems with direct rotor flux orientation. Comparative tests are realized by numerical simulation using the Matlab-Simulink.
