Minimax Output Feedback Regulators
Journal of Dynamic Systems, Measurement, and Control, 1976The linear quadratic regulator problem is considered, and a method for obtaining an optimal output feedback control subject to a minimax performance index is presented. The optimal constant feedback matrix, which denotes the optimal constant feedback gains, is determined by minimizing the effects of the worst value of the initial state on the system ...

Output feedback stabilization of a vibrating gyroscope
Proceedings of 2003 IEEE Conference on Control Applications, 2003. CCA 2003., 2004In this paper we give a solution to the output feedback stabilization problem of a vibrating gyroscope. The system is modelled as an interconnected system, and the coupling terms between subsystems are functions of the uncertain rotation speed. The formulation is made in an LMI framework.

Output Feedback Designs for Output Tracking
2004In Chapters 2 and 3, we developed adaptive state feedback control schemes for linear time-invariant plants with actuator failures characterized by some inputs being stuck at some values not influenced by control action, to achieve state tracking (Chapter 2) or output tracking (Chapter 3).

LQP: Dominant output feedbacks
IEEE Transactions on Automatic Control, 1982An output feedback matrix F will be said to dominate another, \bar{F} , if the cost for F is not higher for any initial condition than the cost for \bar{F} and if the cost is lower for some (perhaps all) initial conditions. The output feedback obtained by, for example, the Levine-Athans approach does not necessarily dominate the open-loop feedback \bar{

Control of linear systems through the use of constant output feedback is considered. Conditions obtained by Levine and Athans [1] that must be satisfied by constant feedback gains in order to be optimal are developed here using an alternate and mechanically simpler approach.

Linear time-invariant discrete-time scalar systems under periodically varying output feedback are considered. Some previous results on pole-placement are summarized, and extensions of these results are presented. The movement of zeros is also discussed.

A new necessary and sufficient condition is derived to decouple linear time-independent multivariable systems through output feedback. As a consequence of this result, an easily computable sufficient condition for output feedback decoupling is obtained which is expressed in terms of the open-loop parameters of the system.

In this paper we present necessary and sufficient conditions for (full) output feedback equivalence of linear control systems. Given two minimal control systems with m inputs n states and r outputs, we give as solution the equality of certain invariants and the existence of solution of a linear system of n(m+r)-mr equations with a number of unknowns ...
