The Design of Dynamic Compensators for Dominance Improvement

This paper deals with the design of dynamic compensator K(s)=K^(-α)s^-α+…+K⁰+K¹s+…+K^βs^β which reduce open loop interaction in a m-input/m-outputmultivariable system.Up to now a(α+β+1)m×(α+β+1)m eigenvalue/vector problemhad to be solved for pseudodiagonalisation.In this paper an improved algorithm wh-ich reduces this problem to a 2×2 eigenvalue/vector problem is presented.Twoexamples designed interactively by computer are included to illustrate the effectiveness of the procedure.
