Improvement of Ride Performance by Damping Force Control based on Bi-linear Optimal Control Applying Piston Speed Dependent Damping Coefficient Limitation

This paper proposes a semi-active suspension control based on Bi-linear optimal control with piston speed dependent damping coefficient limitation. It is difficult to maintain body motion control and smoothness, while typical sky-hook control and Bi-linear optimal control with constant damping coefficient limitation. However, the proposed bi-linear optimal control with piston speed dependent damping coefficient limitation not only achieves body motion control, but also improves smooth ride comfort. The effects of a proposed method has been proven by computer simulations and the control equipped vehicle’s test results.
