Stabilization of Multiloop Systems via the Sensitivity Function
Abstract
The problem studied in this thesis is the stabilization of multiloop systems against individual variations in one or more of the system parameters. A correlation between the stability of a multiloop configuration and the real-frequency behavior of the sensitivity function is derived. From this relationship, a set of stability margins is developed which provide a quantitative measure of the destabilizing effects of variations in each parameter. The margins, referred to as "parameter gain and phase margins" are shown to be generalizations of the familiar gain and phase margins of the single-loop, servo system. The design objective is the realization of a set of specified stability margins; the relationship between these margins and the real-frequency behavior of the associated sensitivity functions gives rise to specification of the sinusoidal response of compensation networks at a set of discrete frequencies.
