Abstract
Traditional model reference adaptive system (MRAS)speed identification is based on the ideal reference model of permanent magnet synchronous.In order to accurately determine the speed of the motor need to know exactly the motor parameters,but the motor runs under different conditions will lead to changes in parameters,which make poor performance of identification system.So introduced a model reference adaptive system based on reactive power of stator current.Combined with vector control and simulation analysis were based on Matlab.The simulation results show that the speed estimation system based on model reference adaptive system of reactive power has good steady-state performance,identify motor speed quickly and use less parameter of permanent magnet synchronous motor.关键词
