Model reference adaptive control system simulation of permanent magnet synchronous motor

In order to study the effect of reference adaptive system model (MRAS) on the permanent magnet synchronous motor (PMSM), we established a current model of adjustable parameters with the angle frequency, which referred to the electromagnetic relationship of the PMSM. Then the output of the PMSM is adjusted by the control of MRAS through the control signal. Under the help of the software of Matlab/Simulink, the simulation model of MRAS control scheme is designed, and gained the successful. The simulation results show that the response time of the MRAS controller is fast, the overshoot is small, the anti-disturbance ability and the steady state error is small when the system parameters are constant.
