Abstract


Permanent magnet synchronous motors(PMSM)have the advantage of not requiring any magnetizing current and easy to control. They are widely used in high performance servo systems. This paper aims at the analysis of the power factor of PMSM, and proposes the control scheme of the power factor.It has great impacts on the energy-saving and the improvement of the power factor of electric netwok.The object of the research of this paper is the surface Permanent Magnetism Synchronous Motor(PMSM). Based on vector control theory, this paper use id=0 control way, make technology with space vector pulse width, select rotational speed and current the control scheme of the two PI regulations of closed circuit, realize control for generator instant moment.At aim of this control scheme, according to the mathematics of surface Permanent Magnetism Synchronous Motor, establish the model of system simulation with MATLAB/SIMULINK, emulate study. Seeing. from emulation result,it has verified possibility and the correctness of this scheme. This paper analyses the power factor and realizes the contol of it in SIMULINK. It proves to be feasible and right via series of simulation.Key Words:PMSM, mathematical model, vector control, PI regulate, power factor
