Two Control Algorithms for the Semi-Active Suspension of Tracked Vehicles

Performances of LQG control under three kinds of combinations of weighting coefficients for a semi-active suspension of tracked vehicle are studied. The fuzzy control rules for the semi-active suspension system are presented based on the dynamics equations and rig experiments. Simulation results illustrate that fuzzy logic control minimizes the vertical acceleration effectively when compared with LQG control under the constraint on the suspension travels.
