A design of automobile cruise control system based on fuzzy PID

Coping with the problem of the automobile cruise control system, a method based on fuzzy PID is proposed. Signal input device, CCS ECU and actuator etc are used to construct the control system. The PID fuzzy control algorithm is proposed. The fuzzy rules and proportion factor of fuzzy output are optimized in MATLAB. It retains the advantages of conventional fuzzy control and meanwhile, it is improved the performance of cruise control system. It proposes fuzzy PID control as control basis. It builds the automobile longitudinal force model of PID and simulated the validation and control effect of system in MATLAB. The results analysis shows that increased in the average response time. Automobile experiment indicates that the system work effectively and stably.
