Design of a vehicular suspension controller by static output feedback

A static output feedback controller is applied to the design of an active suspension model for a quarter-car vehicle, using only the suspension travel displacement and velocity as output variables. The feedback design proposed makes use of recent linear matrix inequalities results from the literature, also allowing to consider the presence of uncertain parameters. Simulations are carried out taking into account the model uncertainty. The results are shown to be as good as the classical linear quadratic regulator which supposes full state availability and precisely known parameters.
