SENSITIVITY ANALYSIS OF CERTAIN NONLINEAR CONTROL SYSTEMS,
Abstract
It is well known that one of the main purposes of applying feedback is to reduce the system dependence or sensitivity to the usually undesirable parameter variations. A method of justifying the application of feedback would be to compare the perturbed responses with the nominal responses of the system with and without feedback control. In this thesis with the aid of the recent developments in the sensitivity theory by Bihovski, Romovic, Cruz, and Perkins, two such comparisons are made. The first one is a nonlinear model of a servomotor and the second one is the diving submarine example of Schoenberger. For these two examples it is shown that feedback control is superior to open loop control in the sense that the former is less sensitive to parameter variations. (Author)
