In this work we investigate bifurcation structures in the chaotic domain of a piecewise linear bimodal map. The map represents a model of a circuit proposed to generate chaotic signals. For practical purposes it is necessary that the map generates robust broad-band chaos. However, experiments show that this requirement is fulfilled not everywhere. We show that the chaotic domain in the parameter space...
In this paper we consider systems which are nonlinear with respect to its variables and to its parameters. A particular case is considered here: an intensity/pressure converter which able us to command an artificial muscle. One of the main problems in control of such system is to have an accurate model and so to know with sufficiently accuracy the different parameter's values. When the system is nonlinear,...
A well-known drawback of classical gain-scheduling methods is that they provide controllers which require to be checked after their synthesis: the immersion of a nonlinear system into a family of linear systems to build local control laws provides a global control law only effective on neighbourhoods. The aim of this paper is to expose a general algorithm able to provide a global control law which...
In this paper we propose to use the important work made in the area of linear robust control to ameliorate the global robustness of a flatness based control. The main idea consists in adding a linear feedback on the nominal flat control. This feedback is calculated on the linearised system of the error tracking. From the linearised system (depending on the desired trajector) is defined a polytopic...
