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.

This monograph couples output regulation with several recent developments in modern control theory. It re-examines output regulation theory to achieve a design of controllers that take into account the physical limiting characteristics of actuators such as saturation. The book provides a solution to the basic problem of finding a controller that achieves internal stabilization, results in a desired performance norm, and renders asymptotic tracking of a reference signal even in the presence of persistent disturbances.

Robust and H_ Control

Published 25 February 2000

H-infinity control theory deals with the minimization of the H-norm of the transfer matrix from an exogenous disturbance to a pertinent controlled output of a given plant. This comprehensive book examines both the theoretical and practical aspects of H-infinity control from the angle of the structural properties of linear systems.
