Worst Case Output of Uncertain Systems

Abstract [en]

The numerical solution of the problem treated in this paper is an important step within a couple of recently developed controller-design procedures, dealing with multivariable or uncertain systems subject to hard-bounded control signals. We determine the worst case output amplitude of stable systems, excited with an input signal that is bounded in amplitude and rate. In the case of SISO systems, this problem can be solved via Linear Programming and a numerical algorithm is presented. This is a significant computational simplification compared to the solution used so far. The same framework can be applied for multivariable systems. A consequence of the Linear Programming approach is that uncertain systems, affinely parameterized in the uncertain parameter vector, can be treated via Quadratic Programming.
