Decoupling linear multiinput multioutput plants by dynamic output feedback: an algebraic theory. (English) Zbl 0603.93029

This paper presents a general algebraic design method for all diagonal input-output maps which can be achieved by a stabilizing two-input-one- output controller for a given plant. The design method is that of two- degree-of-freedom design. This two-degree-of-freedom design enables us to design an input-output map independently of the disturbance-output map and, therefore, requiring the compensator to decouple the input-output map, leaves the stabilizing nature of the compensator intact. Design theory is presented in Section 2. Section 3 characterizes all diagonal input-output maps which can be achieved by the design method stated in Section 2. Examples and conclusions are shown in Section 4.
