A historical review of recent results in robust control is presented. The robust control
problem, ie, the problem of designing accurate control systems in the presence of significant …

A revolution in control theory thought happened in the early 1970s when the dominant focus
of research shifted from optimality to robustness in response to unexpected failures of …

In this paper, the problem of sensitivity, reduction by feedback is formulated as an
optimization problem and separated from the problem of stabilization. Stable feedback …

At publication, The Control Handbook immediately became the definitive resource that
engineers working with modern control systems required. Among its many accolades, that …

This paper expresses limitations imposed by right half plane poles and zeros of the open-
loop system directly in terms of the sensitivity and complementary sensitivity functions of the …

An extension of the backpropagation method, termed dynamic backpropagation, which can
be applied in a straightforward manner for the optimization of the weights (parameters) of …

The robustness of control systems with respect to model uncertainty is considered using
simple frequency domain criteria. Available and new results are derived under a common …

For linear time-invariant multivariable feedback systems, the feedback properties of plant
disturbance attenuation, sensor noise response, stability margins, and sensitivity to plant …

The concepts of principal gain and principal phase are introduced for linear multivariable
systems, and their use in the analysis of feedback behavior is demonstrated. A sufficient …
