Active control for actuator uncertain half-car suspension systems
This chapter designs a non-fragile H∞ controller for a class of active suspension systems with actuator uncertainty. By using Lyapunov stability theory, a nonfragile controller is designed for the purpose of ensuring that the resulting active suspension system is asymptotically stable with a prescribed H∞ disturbance attenuation level. The designed non-fragile H∞ controller is constructed via convex optimization by guaranteeing its sufficient condition in terms of feasible linear matrix inequalities (LMIs). Simulation results are given to show the effectiveness of the proposed control approach.
