Abstract :
The state equation of permanent magnet synchronous motor (PMSM) based on its complex description is deduced. Consequently, the adaptive law of real parameter and real consectary system is extended to complex variant system, based on which an adaptive observer of rotate position is designed. The simulation results of the adaptive observer in different conditions demonstrate its excellent performance
