A new dynamic output feedback compensator design for pole assignment (Q1307603)

A new approach for the design of dynamic output feedback compensator (DOFC) and for pole assignment of linear control systems is proposed. It is applicable for open loop systems either with more outputs than inputs or with at least one stable transmission zeros. Although this DOFS cannot always guarantee arbitrary pole placement of the closed loop system, it has three desirable features: (1) the DOFC poles are subset of the feedback system poles and thus the DOFC stability is guaranteed; (2) the DOFC can implement state feedback control which produces the best performance; (3) the design is decoupled into two pole assignment problems of orders \(r\) and \(n\), respectively, instead of the existing design of order \(n+r\), where \(n\) and \(r\) are the orders of open loop system and DOFC, respectively. Numerical examples are given.
