Mechatronic subsystems are being developed more and more in automotive industry due to their better performance compared to passive components. In this paper, a semi-active suspension system and its control is studied. A feedback control of the suspension system of a quarter car model is described and CRONE methodology applied. As a suspension system design results from a compromise between contradictory goals, an optimal problem is given which provides two CRONE controllers, each with its own strategy. A hybrid control is then introduced to switch between strategies, and refined to reduce switching bump. Control stability is proved using a global Lyapunov function.
