The implementation of CMAC-PID controller based on FPGA

CMAC is a type of local learning neural network with a simple architecture and a quick learning convergence, PID control algorithm is used for the widest range of application at present. Combining both of these advantages, the CMAC-PID controller was designed using the parallel mode and the MATLAB simulation experiments were done. Controller was designed based on VHDL, the research keys were the implementation of the online learning algorithm of CMAC and the closed-loop simulation test of the controller. Ultimately, the controller was implemented in the FPGA. The experiment results indicate that the controller has quick computing speed, high precision and better ability of anti-interfere. It is a new and efficient method to implement IP control module or intelligent control based on a single chip.
