Description
Summary:In this note the design of active suspension control is approached in a Youla parametrization setting, leading to dynamic output feedback controllers calculated by convex optimization. The controllers so designed have the following advantages over the usual ones: (i) they do not require the availability of the full states vector; (ii) the optimization problem may be cast in a true multiobjective fashion; (iii) the method reveals the limits of performance of the physical system under the given costs and constraints. An example is provided in a two-degree-of-freedom quarter-car model with H ∞ , optimization criterion.
