Discrete-Time Output Regulation on Sample-Data Systems

Muwahida Liaquat and Mohammad Bilal Malik

Abstract—In this paper output regulation problem for sampled-data systems with constant exogenous signals is considered. A discrete output feedback controller is designed under the assumption that the regulator equation in discrete-time has a solution. Discretization of the plant and exosystem is carried out by zero order hold equivalence. The goal is to design the complete controller/observer in discrete domain. As an application magnetic levitation is discussed. The simulation results along with the comparison with the continuous-time controller show the effectiveness of the proposed controller.

Index Terms—Discretization, linear systems, output regulation, sampled-data control.
