Sensitivity in Multivariable Control Systems

Journal of Basic Engineering, 1969
Definitions of system sensitivity for linear single variable systems have been extended, in the past, to linear multivariable systems in the form of a sensitivity matrix. The role of the sensitivity matrix in multivariable feedback control systems is studied further in this paper. The sensitivity matrix serves the dual function of governing the effects

Solutions to the combined sensitivity and complementary sensitivity problem in control systems

IEEE Transactions on Automatic Control, 1996
Summary: In a recent paper, a set of necessary and sufficient conditions for the existence of solutions to the combined sensitivity and complementary sensitivity (CSCS) problem in control systems was given. However, a practical method for constructing solutions to this problem was not presented.

Sensitivity and dynamic accuracy of control systems

IFAC Proceedings Volumes, 1964
Publisher Summary This chapter describes sensitivity and dynamic accuracy of control systems. The problem of sensitivity of dynamic systems, and particularly of control systems, with respect to parameter changes occupies a very important place in modern engineering. The interest in this problem is twofold. On the one hand, in the physical realization

Sensitivity of automatic control systems with variable structure

IFAC Proceedings Volumes, 1964
Publisher Summary This chapter discusses the sensitivity of automatic control systems with variable structure. It describes the task of synthesizing control systems for linear plants with variable parameters satisfying specified performance criteria. As one of the indices of dynamic properties of the system, the settling time is considered.

Sensitivity aspects of linear digital control systems

Automatica, 1969
A technique for the sensitivity analysis of linear computer controlled systems is presented. The incremental covariance of estimation error is used to demonstrate quantitatively the deterioration in estimation quality under the perturbed initial conditions, system parameters, plant and measurement noise covariances.

Comments on "Solutions to the combined sensitivity and complementary sensitivity problem in control systems

IEEE Transactions on Automatic Control, 1998
Summary: In the above-mentioned paper, a numerical example is given to show that the Nevanlinna-Pick interpolation formulas appearing in [1] and [2] are incorrect. By comparing [2] with [3] we illustrate that the correct formulas are obtained by simply taking the transpose of the Pick matrix given in [1] and [2].

Engine Control System Sensitivity

SAE Technical Paper Series, 1982
<div class="htmlview paragraph">THIS PAPER describes the use of sensitivity functions to investigate the sensitivity of engine control systems to unknown variations in parameters. The definition of output sensitivity functions and the derivation of their defining differential equations are reviewed.

Sensitivity reduction in modal control systems

Journal of the Franklin Institute, 1974
Abstract The conventional modal control theory is concerned with the problem of determining a state feedback matrix-valued gain which drives the system eigenvalues to prescribed positions. When the parameters of the open-loop system involve certain variations, the closed-loop eigenvalues, obtained by using a feedback gain determined as above, also ...

Sensitivity of linear control systems to large parameter variations

Automatica, 1969
This paper is concerned with the sensitivity of a linear system-quadratic type cost functional to large parameter variations in the description of the linear system. For some class of parameter variations @e and some real number @r, the concept of @r-sensitivity is introduced: @r-sensitivity occurs if the value of the cost functional does not increase ...
