The robustness properties of the linear quadratic regulators for singular systems

TL;DR: It is shown that the optimal regulators for singular systems with an appropriate selection of the feedback gain have the same robustness properties as those in regular systems, namely, at least 60 degrees guaranteed phase margin, infinite gain margin, and 50% gain reduction margin.

Technical Notes and Correspondence The Robustness Properties of the Linear Quadratic Regulators for Singular Systems

TL;DR: In this paper, the LQR robustness properties of singular systems are investigated and it is shown that the optimal regulators for singular systems with an appropriate selection of the feedback gain have the same robust properties as those in the regular systems.
Journal ArticleDOI

New Developments using AI in Fault Diagnosis

TL;DR: The basic idea of a knowledge-based observer-like concept, the so-called knowledge observer, is introduced and the neural network approach for residual generation and evaluation is outlined as well.

Frequency domain approach and threshold selector for robust model-based fault detection and isolation

TL;DR: In this article, the problem of residual generation and evaluation for uncertain dynamic systems is formulated and investigated with the aid of frequency domain approaches and H∞- optimization techniques, based on the parametrization of residual generators, the design of optimal residual generators reduces to an optimization problem that is solved by H ∞-techniques.

Robust Model-Based Fault Detection in Dynamic Systems

TL;DR: In this article, the design of robust fault detection and isolation (FDI) techniques using analytical models for nonlinear and time-varying uncertain systems has been discussed, and an adaptive nonlinear unknown input observer scheme is proposed.
