A note on compensation of multivariable root loci
D.H. Owens · International Journal of Control · 1979
A recently derived computational approach to tine analysis of the asymptotic behaviour of the root locus of a square invertible system Q o(s) is used to construct easily realizable compensation elements. It is demonstrated that the asymptotic directions and pivots can be manipulated at will by the use of dyadic controllers with subsystem dynamics represented by classical compensation elements.
