Abstract. The main result of this paper is to show that a “winding number condition ” which relates to two strictly multivariable linear operators, and which is used in the definition of the...
PROPERTIES OF THE GRAPH TOPOLOGY FOR SCALAR TRANSFER FUNCTIONS ∗ (2008)
Abstract. Necessary and sufficient conditions for the existence of a scalar homotopy in the Vinnicombe metric between two given transfer functions are presented. Previous results show that for...

Fundamental Limits of Worst Case SensitivityTight Bounds for MIMO (2007)
New results are presented, giving performance limits in the form of tight lower bounds on the achievable H1 norm for the closed loop sensitivity for output feedback control of linear time-invariant...

A fault detection filter is designed by minimising the response to confounding noises whilst keeping the fault response constant. A linear quadratic optimisation problem, related to H 2 and H1...
FAULT DETECTION: A CONTROL PHILOSOPHY APPROACH TO DESIGN VIA CONSTRAINED (2007)
Thomas S Brinsmead, Graham C Goodwin
Address as above Abstract: As modern control brings systems nearer their performance limits, the dependence of the system on the controller increases- not only in terms of performance, but also in...
Sensitivity Limitations for Multiple-Input Multiple-Output Plants (2007)
Expressions for tight bounds on the minimum achievable H1 norm for the closed loop sensitivity and complementary sensitivity functions for the output feedback control of linear time-invariant systems...

Multiple model adaptive control, part 1: Finite controller coverings (2000)
Thomas S. Brinsmead, Franky De Bruyne, João Hespanha, Daniel Liberzon, A Stephen Morse
We consider the problem of determining an appropriate model set on which to design a set of controllers for a multiple model switching adaptive control scheme. We show that, given mild assumptions on...

Cost of cheap decoupled control (1998)
It is known that requiring a controlled system to be decoupled may increase costs in terms of some performance measures. However, decoupling may be desirable from an applied perspective. This paper...
