Life lessons from and for distributed MPC – Part 2
Choice of decision makers
This paper and an accompanying
paper (McNamara et al., 2018) revisit the Distributed Predictive Control
(DMPC) literature and seek to establish links with the social
behaviour, focusing in particular on ways in which DMPC could be used to
provide insights into the mechanisms

Life lessons from and for distributed MPC – Part 1
Dynamics of cooperation
This paper and a second accompanying paper (Olaru et al., 2018) explore the potential of Distributed Predictive Control (DMPC) literature to provide valuable insights into social behaviour. In particular this first paper focuses on the mechanisms of group regulation in social sys

Observer-based Sensor Fault Detectability
About Robust Positive Invariance Approach and Residual Sensitivity
This paper considers detectability of deviation of sensors from their nominal behavior for a class of linear time-invariant discrete-time systems in the presence of bounded additive uncertainties. Detectable sensor faults using interval observers are analyzed considering two dist

Active fault isolation
A duality-based approach via convex programming
This paper presents the mathematical conditions and the associated design methodology of an active fault diagnosis technique for continuous-Time linear systems. Given a set of faults known a priori, the system is modeled by a finite family of linear time-invariant systems, accoun

To detect faults in a system we can adopt an observer, designed for the healthy system, and monitor the discrepancy between actual and expected behaviour of the residual (difference between the system output and its estimate). To isolate faults, we can compute the invariant sets

This paper deals with the experimental results of implementing a fault tolerant control (FTC) in a classical ball-on-plate control framework. The work builds on the fact that a robust nominal controller is found to be insufficient in accommodating a sensor fault generated by the

The objective of this work is to analyze the performance of the local monitoring modules of a distributed diagnosis scheme tailored to detect multiple sensor faults in a class of nonlinear systems. The local modules monitor the healthy operation of subsets of sensors (local senso

The objective of this chapter is to present a methodology for computing robust positively invariant sets for linear, discrete time-invariant systems that are affected by additive disturbances, with the particularity that these disturbances are subject to state-dependent bounds. T
