Abstract

This paper is concerned with a unified methodology for sub-optimal design of proportional-integral and proportional-integral-derivative delta domain controllers for SISO plants. Problems of how to satisfy both the nominal as well as robust closed-loop stability and performance are also addressed. The resulting robust delta domain controllers of assumed simple structure can thus be recognised as ones that provide the required stability margin for maximally achievable closed-loop bandwidth in the presence of plant uncertainty. The method is illustrated by numerical examples.
