A multiobjective approach for H/sub 2/ and H/sub /spl infin// active suspension control

This paper presents a methodology for the multiobjective design of active suspension control. The method is based on existing algorithms of optimal control synthesis with cost function employing some weighting of the primary objectives "user comfort", "rattlespace" and "road-holding ability'" The optimal H/sub 2/ and the central H/sub /spl infin// controllers are used as two instances of such algorithms. The method leads to (local) Pareto-optimal solutions and allows the direct specification of controller constraints in terms of that primary objectives. An example shows the superiority of the proposed methodology in relation to classical designs.
