A novel sensorless control technique for permanent magnet synchronous motor (PMSM) using digital signal processor (DSP)

A novel sensorless control scheme for permanent magnet synchronous motor (PMSM) is presented. The rotor position estimation is obtained by the position perturbation algorithm, and high performance of the PMSM is achieved by using the vector control technique. DSP56005 is used to realize the position estimation and vector control algorithms. Experimental results are presented to substantiate the proposed scheme.
