Disturbance Decoupling Control for a Class of Nonlinear Time-Delay System

Abstract

The disturbance decoupling control problem was considered for a class of MIMO nonlinear time-delay systems. Under assumptions, a nonlinear feedback control law is constructed, which ensures that outputs of the closed-loop system are unaffected by disturbances and independent of time-delay. Based on differential geometry theory, sufficient and necessary conditions are derived for the existence of such feedback control law. An example is provided to illustrate the effectiveness of the results in the paper
