ABSTRACT
Permanent magnet synchronous motor as a new type of motor, has the advantages of light weight, high power density, rotor inertia small, high efficiency, can realize the control requirement of fast and accurate, so it is widely used in all walks of life and daily life. The control system of permanent magnet synchronous motor is a nonlinear multivariable, highly coupled complex system, the primary task of research of advanced control algorithms is to establish suitable for permanent magnet synchronous motor mathematical model, and makes analysis, modeling and Simulation of therefore, how to establish a permanent magnetic synchronous model has been the basis of proper control system research permanent magnet synchronous motor.
Based on the analysis of the structure of permanent magnet synchronous motor and the principle of coordinate transformation, the discussion on the control system of permanent magnet synchronous motor, and gives the mathematical model of PMSM ABC static coordinate system, alpha - and beta stationary coordinate and d-q rotating coordinate system is derived based on the mathematical model, and the equivalent circuit of permanent magnet synchronous motor, and discusses the principle of vector control, analysis of the id=0 control, the maximum torque / current control, the weak magnetic control strategy, and on this basis, discussed the control method of permanent magnet synchronous motor, gives the permanent magnet synchronous motor vector control method.
In this paper, through the Matlab/Simulink tool, the vector control system of permanent magnet synchronous motor by the modeling and simulation. Simulation results show that the model is correct, can be used as a further study of permanent magnet synchronous motor model based control.
