An Automatic Sensitivity Time Control System

IEEE Transactions on Aerospace, 1964
A completely transistorized automatic sensitivity time control (ASTC) circuit was designed and developed to operate in conjunction with a side-looking airborne radar surveillance set. The ASTC technique is a closed loop system which automatically controls the radar receiver gain vs range function in accordance with the average signal return.

Sensitivity minimisation in computer control systems

Transactions of the Institute of Measurement and Control, 1990
The sensitivity of linear, shift invariant system models to parameter variations is discussed. Conditions minimising the sensitivity of the system model to these variations are derived, enabling stability margins to be maintained.

Sensitivity of optimal control systems with bang-bang control†

International Journal of Control, 1973
The effects of small parameter variations on the performance index of optimal control systems with initial and final target manifolds, free end time, and bang-bang control are analyzed in this paper. A new approach to the sensitivity equation is presented.

The performance and sensitivity of classical control systems

International Journal of Systems Science, 1978
A definition is given of the performance required from a device such as a multi-variable regulator or servomechanism, and sufficient conditions that, guarantee such performance are derived. These conditions are expressed in terms of the step responses and are useful in design.

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.

On a Procedure for the Calculation of Sensitivity Functions for Optimal Control Systems

IFAC Proceedings Volumes, 1982
Abstract A procedure for the calculation of sensitivity functions for nonlinear optimal control systems is treated in this paper. Determination of sensitivity functions is carried out in two phases by the same programme based on Warner's algorithm. In the first phase, optimality problem is solved. In the second phase, linear sensitivity equations are

On performance sensitivity of optimal control systems†

International Journal of Control, 1972
Formulae for the differential, with respect to plant parameters of an optimized performance index (performance sensitivity), are extended to include hard (instantaneous) as well as soft (isoperimetric) constraints on the control. In particular, this extends to discontinuous and bang-bang controls the Pagurek-Witscnhausen result on the equality of such ...

On sensitivity minimization for linear control system

1980
A linear control system Open image in new window is considered. $$x(t){\mathbf{ }} \in {\mathbf{ }}R^n {\mathbf{ }}u(t){\mathbf{ }} \in {\mathbf{ }}R^m {\mathbf{ }}y(t){\mathbf{ }} \in {\mathbf{ }}R^p {\mathbf{ }}r{\mathbf{ }} \in \Omega \subset {\mathbf{ }}R^q$$ The goal is to find a feedback $$x(t){\mathbf{ }} \in {\mathbf{ }}R^n ...

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 ...
