Defragilization in optimal design and its application to fixed structure LQ controller design
In this work, we present a general methodology to address the recently debated fragility issue in optimization-based modern control systems design. Based on this methodology we have developed aExpand

A sampled-data theory for fixed structure LQ controller design
The fixed structure sampled-data LQ-optimal control problem is discussed. A method is presented to design a discrete controller with fixed structure and order that minimizes a continuous quadratic ...

Dynamic threshold generators for robust fault detection in linear systems with parameter uncertainty
The problem of developing robust thresholds for fault detection is addressed. An inequality for the solution of a linear system with uncertain parameters is provided and is shown to be a valuableExpand

Experimental dependability evaluation of a fail-bounded jet engine control system for unmanned aerial vehicles
This paper presents an experimental evaluation of a prototype jet engine controller intended for unmanned aerial vehicles (UAVs). The controller is implemented with commercial off-the-shelf (COTS)Expand

Parametric uncertainty in sensor fault detection for turbofan jet engine
A method for detecting sensor faults in a turbofan engine is presented. The proposed method consists of an observer with integral action and an adaptive detection threshold. The threshold is computedExpand
