Abstract

This article addresses a new development of robust pole placement design in the delta domain for single-input single-output (SISO) control systems. Problems of how to obtain both the nominal as well as robust closed-loop stability and performance are considered. The approach is based on a robust pole placement methodology that uses two sets of coupled Diophantine equations and the Q-parameterisation paradigm. The method can be applied both for minimum-phase and non-minimum-phase uncertain systems. A numerical example is given to illustrate the method.
