TRIANGULAR DECOUPLING THROUGH LINEAR STATE VARIABLE FEEDBACK

Abstract

The paper studies the problem of triangular decoupling through l.s.v. f. using frequency-domain approaches. The interactor concept and the matrix fraction right description form are used to resolve the questions concerned with this problem and in turn an algorithm is given for triangularization of any right invertible proper system by using l.s.v.f. alone. The paper describes the use of triangular decoupling as an intermediate step for exact decoupling of systems having unstable decoupling zeros.
