The Research on Vehicle Anti-Braking System Control Algorithm Based on Immune PID Control

Abstract

Because the classic PID control doesn’t satisfy the demand of automobile ABS in all conditions and it is short of an ability of identifying road surface, fuzzy control is short of an ability of remove systemic stable error and it doesn’t make automobiles keep higher control precisions. a dynamic mode of the wheels is built when an automobile is braking at first, aiming at automobile ABS, a immune PID control algorithm based on classic PID is presented and used in automobile ABS system. Compared with the classic PID control algorithm and fuzzy control algorithm, the simulation result shows that the immune PID control algorithm has a shorter stabilization time, a smaller excess of system output, fewer response time and shorter braking distance, it is superior to the classic PID control algorithm and fuzzy control algorithm. The immune PID control algorithm has a higher application value.
