In order to improve the operation performance of PMSM,the Jaya algorithm is optimized and applied to the parameter identification of PMSM.In fact,the performance of PMSM drive system with vector control depends on PI regula-tor.These regulator parameters will be adjusted according to the identified PMSM motor parameters.Therefore,in order to improve the operation performance of permanent magnet synchronous motor,the parameters of PI regulator need to be ac-curately adjusted and suitable for the parameters of PMSM.The result of PMSM parameter identification is verified by MAT-LAB simulation modeling,which proves that the optimization has certain positive effect.
