A descriptive, easy to implement approach for the self sensing operation of permanent magnet synchronous machines (PMSM) is presented in this paper. Position and speed identification is performed by solving a nonlinear equation system with a simple, real-time capable algorithm. The approach considers nonlinear magnetic effects by means of flux linkage maps and thus provides reliable position and speed identification in the full speed and torque operating range for stationary and dynamic operation. An experimental proof of functionality is presented.
