Permanent magnet synchronous motors（ PMSM） control system has multi-rate sampling charac-teristic in itself on the system input and output. The model transformation matrix was proposed based on polynomial transformation technique and the dual-rate mathematical model of PMSM was induced under the current and voltage, and the extended parameters vector and regressive model of dual-rate sampled system was acquired. The residual was used to estimate the unmeasurable noise, and then the residual based extended least squares （ DR-RELS） was proposed and used to the parameters identification, and the convergence properties of the algorith
