The fuzzy logic control for suspension systems of tracked vehicles

A scheme of fuzzy logic control for suspension systems of tracked vehicles was presented. A mechanical model for a half of a tracked vehicle was established, which is totally eight degrees of freedom including the vertical motion and rotation of the tracked vehicle. In contrast to most previous studies, the coupling effect between the vertical and rotational motions of suspension system of the tracked vehicle was considered. In addition, the different combinations of control forces were investigated, and a theoretical limit for the rotation control was discovered. The simulation of fuzzy logic control under road surfaces of sine and random excitation shows that the acceleration and pitch angle of suspension system can be controlled efficiently.
