NonLinear Robust Control: Theory and Applications

Abstract

There are three main components to the work: Nonlinear Robust Escape, Nonlinear Hr. and Nonlinear Robust Tracking. For the first, we use a numerical method based on generalized characteristics. An application to the compressor stall problem is given. For the second component, we have developed a method for isolating the 'correct' solution in the case of fixed feedback control, This is extended to some active control cases as well. We have employed the generalized characteristics method on the Aerospace Plane Ascent problem and verified that it does indeed attenuate the disturbances. For the third component, we are generating software for Robust Tracking of nonlinear systems with state spaces of several dimensions. There are some open questions regarding the numerics in this case.
