Abstract : In this study, we reanalyze the global regulation problem for an input-delayed chain of integrators by output feedback. Our main objective is to achieve the faster/improved system regulation over the existing result. We propose a reduced-order observer based output feedback controller with a dynamic gain-scaling factor to achieve our main objective. The key feature of our control method is a newly designed reduced-order observer coupled with a dynamic gain-scaling factor. We analytically show that the controlled system is regulated with improved performance over the existing result. An example is given for illustration.

Keyword : Chain of integrators, gain-scaling factor, output feedback control, reduced-order observer, unknown time-varying input delay.
