Power Factor Control

For the traditional sensorless vector control systems of permanent magnet synchronous motor, a new sensorless vector control method is proposed based on the power factor control. On the basis of analysis of the mathematical models for the permanent magnet synchronous motor, established a power factor voltage reference frame system. The rotor position and speed is estimated by the control of power factor angle, and then from the point of view of efficiency drive to configure the stator current. This stator current is arranged in the vicinity of the current minimum trajectory. This method not only can control the speed, but also ensure high power factor and high drive efficiency of the permanent magnet synchronous motor. The simulation results proved the effectiveness and feasibility of this control method.

This paper briefly introduces the vector control theory in permanent magnet synchronous motor (PMSM) ，and gives the block diagram of its drive system on this base. In order to realize complete digitized control and make capability of the system very well, we use TMS320F2407 chip to achieve the control of PMSM。 This paper gives the detailed software and hardware realization projects. The control method of whole system can be realized by writing programs. Experimental results show that the system is compact, and has good static and dynamic characteristics.

Field Oriented Vector Control

This template illustrates the control system of permanent magnet synchronous motor(PMSM) which uses field oriented vector control(field oriented vector control). PMSM is a complex, strong coupling and nonlinear system. And field oriented vector control could provide good performance as well as the PI controller setted with well parameter matching. Whereas limited by the number of voltage vector, the other control method of PMSM, direct torque control, could not satisfy accurate control when the machine running with a low speed. So modulation of the whole system is built here to realize closed-loop field oriented vector control control by keeping id=0 , and the machine model and the transformation among different coordinate system are discussed. The system is verified effective and feasible.
