摘要
Abstract
In this paper,a control method of estimating the rotor speed based on MRAS for interior permanent magnet synchronous motor (IPMSM) in the flux-weakening field is presented. The permanent magnet synchronous motor is considered as reference model and the stator current mathematical model containing estimated parameters is regarded as adj ustable model,an adaptive law based on Popov stability theory is derived.Meanwhile,considering the case of non-equal quadrature axis inductance of salient pole motor,the speed identification formulae applying to both non-salient pole motor and salient pole motor are obtained.The simulation results indicate that speed identification algorithm can accurately identify the speed of IPMSM in the flux-weake-ning field and the identification results respond quickly in system dynamic process.关键词
