Adaptive fuzzy logical control for impact absorbing

A new adaptive fuzzy logical control (FLC) strategy using a hybrid Taguchi genetic algorithm (HTGA) is proposed to absorb the impact of car body caused by road bump. The controller consists of two control loops. The inner open loop controls a nonlinear magnet-orheological (MR) damper to achieve tracking of a desired force. The outer loop implements a fuzzy logic controller using HTGA. The HTGA is used to tune the membership functions and control rules of FLC with initial skyhook control rules. To verify the control performance, simulation and road test of the adaptive FLC are carried out. The simulation and experiment results show that adaptive FLC can achieve smaller acceleration peak and shorter adjusting time than sky-hook and passive system under bump input.
