Optimal active suspension control based on a half-car model

Simple yet, in practice, meaningful state-space formulations of the optimal suspension control problem for a half-car 2D vehicle model are considered. By using an efficient equivalent representation, a complete analytical solution of the related fourth-order linear quadratic problem is obtained. The problem structure and associated analytical results are used to deduce a number of important generic properties of the optimal solution, and these in turn form a basis for global, centralized, and decentralized optimal suspension performance studies
