Active Suspension Control Strategy Based on Co-simulation Between Matlab and Recurdyn

The whole vehicle active suspension with seven degrees was established to improve the riding comfort performance; the fuzzy controller was designed with suspension relative displacement and suspension of the relative speed as input and road excitation level as output to judge the size of the road excitation. The road excitation was further divided into 12 grades, optimal feedback gain by adjusting the weights on the different levels of road excitation was obtained, and optimal control on the road of any grade to achieve the overall performance improvement was achieved. Through the joint simulation of Matlab and Recurdyn the effectiveness and feasibility of this control strategy are verified
