Robust synthesis of feedforward compensators
Copyright policy )Robust synthesis of feedforward compensators
Summary: The design of a feedforward compensator for robust \({\mathcal H}_\infty\) or \({\mathcal H}_2\) 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 \(H_\infty\) performance, the design problem is reduced exactly to a state-space LMI, and extensions to \({\mathcal H}_2\) performance are discussed. An example illustrates the application of these techniques to a two-degree-of-freedom control design.
