Dual Dsp And Fpga-based Brushless Dc Motor Servo Control System Design

The purpose of the thesis is try to develop a high-performanced experiment platform for multi-motor control system, testing control algorithm, and increasing the frequency of the current loop father.The thesis use the Brushless Direct Current Motoras an controlled object, using TMS320F2812, TMS320C6416 and FPGA as the nucleus-unit, completing the design of the hardware, the software and the triple-loops which includes position loop, speed loop and current loop, and making the basic research and practice of the key part.The hardware circuit of the system use FPGA as the central unit of the signals for reconfiguration and updating. The design of the hardware circuit also include: communication circuit between DSP, power supply circuit, ADC/DAC circuit and other circuits.The software design of the system is mainly consist of the main program, the hold-subprogram, the remote writing-subprogram and the interrupt subprogram. The main program finished the initializtion of the chip. The hold-subprogram finished guiding, tracking and holding. The remote writing-subprogram finished on-line updating program. The interrupt subprogram finished the tasks of digital PID control algorithm and PWM generating.Finally, a prototype instrument is developed; the experimental work and the partial experimental results are accomplished. The results of experiment show that the project proposed by the thesis is feasible. The achievements of the research have very important reference for continual research.
