Robust Controller Design

We propose a technique that extends the uses of robust stability analysis (RSA) theorems in a particular class over robust controller design of linear systems subjected to various classes of nonlinear time-varying uncertainties. The technique is based on a new approach of forcing some surfaces in n-space to have a certain relative orientation. A numerical example is included to demonstrate its effectiveness.
