Abstract
A study is made of the destabilizing effects of variations in a system's parameters. It is shown that the sensitivity function provides a quantitative measure of the system stability relative to a parameter. These measures, the parameter gain and phase margins, are multiloop generalizations of the familiar gain and phase margins in the servo literature.Keywords
