On the design of output feedback for finite and infinite pole
A new result of the problem of pole assignment by output feedback is presented. A simple condition is given under which min (n, m + r − 1) closed-loop poles can be assigned arbitrarily by a gain output feedback, where n, mand r are the dimensions of the state, output and input vectors, respectively.
A design technique which uses a weighted least-squares approach for the solution of the output feedback pole-assignment problem is presented.
