Reduction of the Cost of Feedback in Systems with Large Parameter Uncertainties.

Abstract

This work deals with the synthesis of feedback systems to achieve specified performance tolerances, despite large uncertainty in a constrained part of the system, denoted as the plant. Part of this work deals with linear time-invariant (lti) plants where the cost of feedback, if lti compensation is used, is primarily in the bandwidth of the feedback loop being much larger than that of the system as a whole - making the system very sensitive to sensor noise. Here, the objective is to reduce the loop bandwidth by means of non-lti compensation. The result is a very significant reduction in loop bandwidth and with it, system sensitivity to sensor noise.
