Physical, safety or technological constraints induce that the control actuators can neither provide unlimited amplitude signals nor unlimited speed of reaction. The control problems of combat aircraft prototypes and satellite launchers offer interesting examples of the difficulties due to these major constraints.

Neglecting actuator saturations on both amplitude and dynamics can be source of undesirable or even catastrophic behavior for the closed-loop system (such as loosing closed-loop stability).

Such actuator saturations have also been blamed as one of several unfortunate...

Creating some links between control feedback and biology modeling communities based on similarities in modeling, observing and perceiving alive structures, and analyzing interconnections between biological structures and subsystems was the main objective of this volume.

In this context, biology systems need appropriate analysis tools due to their structure and hierarchy, complexity and environment interference, and we believe that these aspects may generate interesting research topics in control area. Indeed, several works, raising the potential impact of control developments to...

In practical control problems, many constraints have to be handled in order to design controllers which operate in a real environment. By combining results on robust control and saturating control, this book attempts to provide positive help for practical situations and, as one of the first books to merge the two control fields, it should generate considerable interest in scientific/acad emic circles. The ten chapters, which deal with stabilization and control of both linear and nonlinear systems, are each independent in their approach - some deal purely with theoretical results whilst others...

This monograph details basic concepts and tools fundamental for the analysis and synthesis of linear systems subject to actuator saturation and developments in recent research. The authors use a state-space approach and focus on stability analysis and the synthesis of stabilizing control laws in both local and global contexts. Different methods of modeling the saturation and behavior of the nonlinear closed-loop system are given special attention. Various kinds of Lyapunov functions are considered to present different stability conditions. Results arising from uncertain systems and treating...

Le robot parallA]le Par2, conAu pour des opA(c)rations industrielles de prise et dA(c)pAt A haute vitesse et haute prA(c)cision, subit des vibrations importantes A la fin d'un dA(c)placement. Pour minimiser ces vibrations, l'utilisation d'A(c)lA(c)ments piA(c)zo-A(c)lectriques autour des bras du robot est proposA(c)e. L'identification en boucle ouverte des modes flexibles du robot, A 2,5kg de charge sur la nacelle et A la position d'arrAat, est faite utilisant une technique basA(c)e sur les sous-espaces. Deux modA]les sont identifiA(c)s, un pour la synthA]se des contrAleurs et un autre pour...
