Issues in Algebraic Control Theory

Abstract

A unified view of recent results in the algebraic theory of linear, time-invariant multiinput-multioutput control systems is presented, with emphasis on the unity-feedback system (one-degree-of-freedom design) and the more general two-input two-output plant and compensator configuration (four-degrees-of-freedom design). The issues of stability, parametrization of all stabilizing compensators, achievable input-output maps and decoupling are discussed.
