NON INTERACTING CONTROL BY MEASUREMENT FEEDBACK

by J.W. van der Woude In this paper we shall solve the problem of non interacting control by measure-ment feedback for systems that in addition to a control input and a measure-ment output have two exogenous inputs and two exogenous outputs. That is, we shall derive necessary and sufficient conditions that can actually be verified for the existence of a measurement feedback compensator such that the transfer matrix of the resulting closed loop system. when partitioned according to exogenous inputs and outputs, has off-diagonal blocks equal to zero
