Abstract:

As for the problem that BP neural network PID control algorithm is complex and hard to implement, a scheme that uses DSP to implement the algorithm is presented, and the external function interfaces are implemented in FPGA. The controller prototype is quickly designed with the help of RTOS(DSP/BIOS) provided by TI. Compared with the traditional PID controlling, the experiment  using this controller to control the velocity of the servo motor shows that the scheme can meet the requirements of the realtime characteristics and the control performance.
