Position and Speed Estimation for a Permanent Magnet Synchronous Motor Rotor Using Composite Second Order Generalized Integrator
摘要
Abstract
Traditional back-EMF observer based on the state estimation causes a phase lag,which will introduce mean deviation of estimated angle for permanent magnet synchronous motor(PMSM)rotor position estimation.This paper proposed an improved back-electromotive force(back-EMF)observer with zero-phase lag.In order to eliminate harmonics and high frequency noises caused by the control algorithm,dead time effect,load disturbance,and other effects,the Second Order Generalized Integrator-Frequency Locked Loop(SOGI-FLL)algorithm was introduced to PMSM position and speed estimation areas.In this paper,Composite SOGI-FLL(CSOGI-FLL)algorithm was proposed to improve the dynamic performance of position and speed estimation and to enhance the capability to reject harmonics and noises.Finally,we set up an experimental platform and verified the effectiveness of the method through steady-state and dynamic experiments关键词
