Research on field oriented control system of induction motor based on computer

In this paper, the basic principle of field oriented control is studied, and a field oriented control system of induction motor with computer as controlling core and DSP TMS320F2812 as the motion control chip is designed. The intelligent power module (IPM) is used as the main switching device of the inverter circuit, and the interface circuit between IPM and DSP is designed. An interactive control software is designed in Visual C++ environment, and the FOC algorithm program is compiled in this software framework. Experimental results show that the system achieves good control effect, and good dynamic and steady-state performance.
