Abstract: 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 is designed using the parallel mode and the Matlab simulation experiments are done. Controller is designed based on VHDL, the research keys are the implementation of the on-line learning algorithm of CMAC and the closed-loop simulation test of the controller. The controller is 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.
