Application research for resilient control of the welding process systems with pole constraints

Abstract

The welding process is usually regarded as an uncertain sampled-data system. In this paper, the problem of resilient control for a class of uncertain sampled-data system is investigated, then pole contraints theory and the linear matrix inequality approach are incorporated to design resilient controller against possible perturbation, which results in sampled-data system is D-stable, moreover, the existence condition and the design approach of resilient controller are derived. Finally, simulation examples are presented to illustrate the effectiveness of the proposed algorithm.
