Switched controller design

TLDR: In this article, a high order plant is controlled at each time instant by one of a set of low order controllers, each designed to control one part of a partial fractions expansion of the plant.

Abstract: A method of control is proposed whereby a high order plant is controlled at each time instant by one of a set of low order controllers, each designed to control one part of a partial fractions expansion of the plant. The method is motivated toward the control of flexible structures, such as large space structures, exhibiting large model order, model uncertainty, and decentralisation. Certain switching algorithms are presented, and simulation results demonstrate the efficacy of such methods. These results perhaps point one way forward for tackling difficult control problems.
