Minimax Output Feedback Regulators

Journal of Dynamic Systems, Measurement, and Control, 1976
The 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 ...

LQP: Dominant output feedbacks

IEEE Transactions on Automatic Control, 1982
An 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{

Output feedback stabilization of a vibrating gyroscope

Proceedings of 2003 IEEE Conference on Control Applications, 2003. CCA 2003., 2004
In 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

2004
In 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).

Periodic output feedback

1982 21st IEEE Conference on Decision and Control, 1982
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.

Output feedback control

Proceedings of the 37th IEEE Conference on Decision and Control (Cat. No.98CH36171), 2002
Nash game type of multiobjective output feedback control problems are considered. Sufficient conditions for the existence of optimal controllers are obtained for both finite horizon and infinite horizon problems.

Output regulation of singular nonlinear systems by output feedback

Proceedings of the 40th IEEE Conference on Decision and Control (Cat. No.01CH37228), 2002
A necessary and sufficient condition for the output regulation problem to be solvable by output feedback reduced-order normal controllers is derived, which can be constructed explicitly.

Output Feedback Control

1993
The design of the optimal linear full state regulator requires the measurement of all system states. In many practical applications, this is not feasible due to either the high cost of the state measurements or the inaccessibility for measurement of some of the system states.

Output feedback equivalence

2007 European Control Conference (ECC), 2007
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 ...
