Dissertation/Thesis Abstract

A measurement based approach to designing fault-tolerant controllers for multivariable systems
by Kallakuri, PavanaSirisha, Ph.D., Tennessee State University, 2016, 80; 10158554
Abstract (Summary)

This research introduces two new methodologies to design a set of controllers such that every controller in the set preserves closed-loop stability of a given multi variable plant under prescribed loop failures. The proposed approaches differ from existing techniques in two ways: First, these methods are strictly based on frequency response data of the plant that can be easily measured by experiments. No mathematical models or system identification processes are used. Second, while most control design methods find one controller, the proposed methods design a set of controllers satisfying the control objective. Two approaches are presented with examples illustrating the controller design. Integrity test results of the designed controllers under pre-specified loop failures are also presented.
