Research on Vehicle Anti-braking System Control Algorithm Based on Fuzzy Immune Adaptive PID Control

A fuzzy immune adaptive PID control algorithm for ABS system is presented after analyzed the lack of traditional slip rate ABS control algorithm, combining with the biological immune principle and the adaptive ability of fuzzy logic ratiocination. And the fuzzy immune PID controller adjust the proportional coefficient, the fuzzy controller adjust the integral and differential coefficient. Compared with the PID control algorithm, fuzzy control algorithm, fuzzy PID control algorithm and fuzzy immune adaptive PID control algorithm, the simulation results indicate that the method has characteristics of small overshoot, fast response, shorter braking distance and strong anti-interference ability and robustness. There is a higher application value in ABS control system.
