Research on Design of BLDCM Controlling System Based on FPGA

Abstract:

Brushless dc motor is widely used in high electric field because of its simple structure, large power density, excellent speed regulating performance, and low noise characteristics. This paper describes a brushless DC motor real-time control system based on FPGA. The DC motor is controlled by PWM model and control model which simple the circuit; Calculating the rate of motor by determining the impulse width of n. hall sensor signal; Adopting the soft-core processor embedded in FPGA process increment PID arithmetic control, improve the system real time performance. Experimental results show that the hardware and software are reasonable, owning very good reliability and real time performance. The control system's hardware circuit was designed and implemented such as FPGA periphery circuit, drive circuit, current detecting circuit and so on. And the control arithmetic of current loop, position loop and speed loop were designed and the closed loop control of control system in hardware was achieved.
