Fault detection and isolation of nonlinear systems : an unknown input observer approach with sum-of-squares techniques

Xu, Jun; Lum, Kai-Yew; Xie, Lihua; Loh, Ai-Poh (2012)

This paper presents a novel nonlinear unknown input observer (UIO) design method for fault detection and isolation (FDI) of a class of nonlinear affine systems. By using sum-of-squares (SOS) theory and Lie geometry as the ...

Cooperative control in HNMSim — a 3D hybrid networked MAS simulator

Xu, Jun; Xie, Lihua; Khanna, Nitish; Chee, Wei Hong (2012)

A multi-purpose 3D simulator named HNMSim (hybrid networked multi-agent system (MAS) simulator) with application in cooperative control is presented in this paper. Based on USARSim (Unified system for automation and robot ...

Vision-based multi-agent cooperative target search

Hu, Jinwen; Xie, Lihua; Xu, Jun (2012)

This paper addresses vision-based cooperative search for multiple mobile ground targets by a group of unmanned aerial vehicles (UAVs) with limited sensing and communication capabilities. The airborne camera on each UAV has ...

Improved stability criteria for piecewise affine systems based on partition- and vertex-dependent Lyapunov functions

Xu, Jun; Xie, Lihua (2012)

In this paper, we present two improved stability criteria for a class of piecewise affine systems. First, by applying a partition-dependent Lyapunov function, we present a stability result based on copositive matrices which ...
