Abstract :
This paper exploits the multiobjective control technique to design an output-feedback active suspension. The ride performance is characterized by the H;2 norm, while requirements for having good handling and respecting structural constraints and actuator saturation are specified by the generalized H;2 norm. The active suspension problem is then formulated in a mixed H;2/generalized H;2 control problem, and an output-feedback solution is derived using LMI optimization. Simulation results for a half-car model are discussed.
