TLDR
In this paper, a method is proposed for the design of constant gain feedback control laws for linear multivariable discrete-time systems which reduce trajectory sensitivity to small system parameter variations and ensure the closed-loop eigenvalues at the origin.Abstract:
A method is proposed for the design of constant-gain feedback-control laws for linear multivariable discrete-time systems which reduce trajectory sensitivity to small system parameter variations and ensure the closed-loop eigenvalues at the origin The given quadratic index of performance including a sensitivity term is minimized in an average sense An efficient computational procedure based on direct cost optimization using gradient type algorithm is also reported An example is worked out to illustrate the proposed techniqueread more

Techniques in Deadbeat and One-step-ahead Control
TL;DR: In this paper, the development of deadbeat control and one-step-ahead control were compared and contrasted, and the unification of the two areas was discussed, and some possible points of confusion were identified.

Sensitivity reduction by state derivative feedback.
TL;DR: In this paper, the sensitivity of state feedback control systems can be reduced by adding additional state derivative feedback, for a fixed closed-loop eigenstructure, and the price of this sensitivity reduction is in general noise response amplification.

A connection between state-space and doubly coprime matrix-fraction descriptions of multivariable systems
Chun-Hsiung Fang,Fan-Ren Chang +1 more
TL;DR: In this paper, explicit formulas for doubly coprime matrix fraction descriptions (MFDs) of the transfer matrix of a linear time-invariant state-space system are given in terms of a controllable and observable state space realization of the transferred matrix.

Sensitivity Reduction and Robustness
TL;DR: In Chapters Two to Five the authors devote their attentions primarily to issues regarding parameter-sensitivity analysis, and incorporate in control synthesis algorithm any information regarding possible discrepancies in system “output”, in order to generate new controllers that can stand against the consequences of some possible uncertainties.

Solution of the optimal constant output feedback problem by conjugate gradients
H. Horisberger,P. Belanger +1 more
TL;DR: The problem of finding the optimal, constant output feedback matrix for linear time-invariant multivariable systems with quadratic cost is reconsidered and simple formulae for the gradient matrix are developed and used in a Fletcher-Powell-Davidon algorithm.

Optimization of linear systems of constrained configuration
TL;DR: In this article, it is shown that for each of these criteria the gradient with respect to the feedbacks can be calculated by a uniform method and the solution may then be found either directly or by a descent procedure.

Deadbeat control of linear multivariable discrete-time systems
TL;DR: In this paper, a simple closed-form control law for the deadbeat control of a class of linear multivariable discrete-time systems is presented. But it does not consider the nonlinearity of linear systems.
