The design of a feedforward compensator for robustH1 or H2 performance under structured uncertainty is considered. For linear time-invariant uncertainty, a convex method based on linear matrix inequalities (LMI’s) across the frequency variable is given. For nonlinear or time-varying perturbations and H1 performance, the design problem is reduced exactly to a state-space LMI, and extensions to H2 performance are discussed. An example illustrates the application of these techniques to two-degree… CONTINUE READING
