Abstract: Lowspeed and largetorque compound permanent magnet synchronous motor(CPMSM) is one kind of permanent magnet synchronous motor(PMSM), which has the characteristic of lowspeed and largetorque and is widely applied in many areas. In order to solve the problems of the control of CPMSM, adaptive observer was adopted as one sensorless method. The model of adaptive observer was established and analyzed based on the simulation of Matlab. Parameter identification was also used to improve the stability of the system. The result of simulation proves the feasibility of adaptive observer as one sensorless method.
Key words: compound permanent magnet synchronous motor(CPMSM); adaptive observer; parameter identification
