Loop Transfer Recovery (LTR) is part of the Communications and Control Engineering Series (CCES) edited by Professors B.W. Dickinson, E.D. Sontag, M. Thoma, A. Fettweis, J.L. Massey and J.W. Modestino. Loop Transfer Recovery deals with several issues of analysis and design of the Loop Transfer Recovery (LTR) problem. It discusses when and how an LTR is possible and outlines different controller structures and the available design freedom. An explanation of the actual design methods for accomplishing an LTR is given. Besides dealing with observer based measurement feedback controllers, which are commonly used for LTR, a new controller with a different architecture which out performs observer based controllers is presented. This publication will be of benefit to anyone who has completed a first graduate course in linear systems and state-space methods, together with an elementary knowledge of Linear Quadratic Control.
