Zusammenfassung:	This paper built the adjustable current model which uses the PMSM itself as a reference model with the parameter of speed of revolution adjustable. The self-adaptive law based on Popov hyperstability theory was deduced. The control scheme of PMSM Sensorless control technology based on MRAS was built. The control technology was simulated with Matlab/Simulink software. As the results of the simulation proved, this control technology is simple and effective, with considerable high precision in speed estimation, and also has nice steady state response and transient state response performance, besides, it is also capable of anti-jamming with load interfere.
