Taking into account the variations of the environment is a means of improving performances of roll stabilisation systems. The ship behaviour is modelled as a MIMO LPV system. A methodology is presented which leads to a gain-scheduled control law. The synthesis is based on multi-objective optimisation, and on the representation of the standard system as a polytopical system, which depends on shi...

We use Fourier analysis to investigate the instability of an equal-order mixed nite element approximation method for elliptic incompressible ow equations. The lack of stability can be attributed to the fact that the associated discrete LBB (Ladyzhenskaya-Babu ska-Brezzi) constant tends to zero as the mesh size is reduced. We develop a stabilisation approach that is appropriate to the periodic s...

We propose a new simple algorithm to make use of the sensor orientation information in 3D Electromagnetic Articulography (EMA) for computational head stabilisation. The algorithm also provides a well-defined procedure in the case where only two sensors are available for head motion tracking and allows for the combining of position coordinates and orientation angles for head stabilisation with a...

Application of the normalised HN loop-shaping technique for design and simplification of damping controllers in the LMI framework is illustrated. A linearised model of the power system is preand post-compensated using the loop-shaping approach. The problem of robust stabilisation of a normalised coprime factor plant description is translated to a generalised HN problem. The solution is sought n...

Isolated dislocations of the navicular are rare injuries; we present our experience of six cases in which the navicular was dislocated without fracture. All patients had complex injuries, with considerable disruption of the midfoot. Five patients had open reduction and stabilisation with Kirschner wires. One developed subluxation and deformity of the midfoot because of inadequate stabilisation ...

Herman’s self-stabilisation algorithm allows a ring of N processors having any odd number of tokens to reach a stable state where exactly one token remains. McIver and Morgan conjecture that the expected time taken for stabilisation is maximised when there are three equally-spaced tokens. We prove exact results on a related cost function, and obtain a bound on expected time which is very close ...

Application of the holographic interferometry and speckle photography in the primary stability determination of a mandible undergoing the bilateral sagittal split osteotomy (BSSO) is described. Measurements were carried out on Synbone models of human mandibles representing three different techniques of stabilisation. The maximum value criterion of the cut edge displacement components was used f...

An output stabilisation technique for infinite dimensional bilinear systems is presented. It consists in studying the asymptotic behaviour of such a system only on a subregion of its geometrical domain, so we give sufficient conditions to obtain a stabilising control. Also, we concentrate on the determination of the control which ensures regional stabilisation by minimising a given performance ...
