Optimal active suspension control based on a half-car model: an analytical solution

Abstract

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