In this paper, the dissipativity-based dynamic output feedback controller (DOFC) design for Semi-Markovian jump systems under stochastic cyber-attacks is first proposed. It assumed that time-varying uncertainties obey Bernoulli-distribution and transition probability matrix partially accessed. By utilizing technique, sufficient conditions existence of DOFC are obtained to ensure exponential sta...

This paper deals with the stabilization of a class of uncertain stochastic hybrid systems. The uncertainties are norm bounded type. Under the complete access to the system mode a dynamic output feedback controller that makes the closed-loop dynamics of this class of systems regular, impulse-free and stochastically stable is designed. The state space matrices of this controller are the solution ...

Force controlled manipulation is a common technique for compliantly contacting and manipulating uncertain environments. Visual servoing is effective for reducing alignment uncertainties between objects using imprecisely calibrated camera-lens-manipulator systems. These two types of manipulator feedback, force and vision, represent complementary sensing modalities; visual feedback provides infor...

For linear control systems, we add a Luenberger observer to extend the state feedback hybrid loop designs of (Prieur et al., NOLCOS 2010) and (Fichera et al., ADHS 2012), to the output feedback case. This defines an output feedback controller. The hybrid loop consists in a continuous-time dynamics when the estimate of the state leads to a non-increase of a suitable Lyapunov-like function, and i...

In this paper we define a bisimulation concept for some very general models for stochastic hybrid systems (general stochastic hybrid systems). The definition of bisimulation builds on the ideas of Edalat and of Larsen and Skou and of Joyal, Nielsen and Winskel. The main result is that this bisimulation for GSHS is indeed an equivalence relation. The secondary result is that this bisimulation re...

The paper presents a feedback scheduling mechanism in the context of co-design of the scheduler and the control tasks. We are particularly interested in controllers where the execution time may change abruptly between different modes, such as in hybrid controllers. The proposed solution attempts to keep the CPU utilization at a high level, avoid overload, and distribute the computing resources ...

Fluid film forces are generated in multirecess journal bearings by two types of lubrication mechanism: the hydrostatic lubrication in the bearing recesses and hydrodynamic lubrication in the bearing lands, when operating in rotation. The combination of both lubrication mechanism leads to hybrid journal bearings (HJB). When part of hydrostatic pressure is also dynamically modified by means of hy...

We define controllability for hybrid systems as the existence of correct control-laws that transfer the hybrid plant between pre-defined subsets of the hybrid state-space. A methodology for analyzing controllability and synthesizing control-laws for a class of hybrid systems, applicable expecially in batch control, is proposed. We use a framework consisting of a hybrid plant and a hybrid contro...
