Orientational hysteresis in swarms of active particles in external field

, 2015
Structure and ordering in swarms of active particles have much in common with condensed matter systems like magnets or liquid crystals. A number of important characteristics of such materials can be obtained via dynamic tests such as hysteresis.

Polytopic Observer Design for LPV Systems Based on Minimal Convex Polytope Finding

Journal of Algorithms & Computational Technology, 2009
Linear Parameter Varying (LPV) systems are models widely encountered in the engineering field. In this paper, a systematic method is provided to design a polytopic observer whose goal is to reconstruct the state of discrete-time LPV systems.

Robust Quasi–LPV Model Reference FTC of a Quadrotor Uav Subject to Actuator Faults

International Journal of Applied Mathematics and Computer Science, 2015
A solution for fault tolerant control (FTC) of a quadrotor unmanned aerial vehicle (UAV) is proposed. It relies on model reference-based control, where a reference model generates the desired trajectory.

Model Identification of Linear Parameter Varying Aircraft Systems

Proceedings of the Institution of Mechanical Engineers, Part G: Journal of Aerospace Engineering, 2006
This article presents a parameter estimation of continuous-time polytopic models for a linear parameter varying (LPV) system. The prediction error method of linear time invariant (LTI) models is modified for polytopic models. The modified prediction error method is applied to an LPV aircraft system whose varying parameter is the flight velocity and ...
