the paper studied the exponential stability of general stochastic hybrid systems. First Lyapunov asymptotic exponential stability theorem is extended to general stochastic hybrid systems. Second the stabilization of linear stochastic systems is discussed, and a sufficient and necessary condition is proposed. Finally a second-order example is delivered to illustrate the approach.

A flexible, ubiquitous, and universal solution for management of distributed dynamic systems will be presented. It allows us to grasp complex systems on a higher than usual, semantic level, penetrating their infrastructures, also creating and modifying them, while establishing local and global dominance over the system organizations and coordinating their behavior in the way needed. the approach may allow the systems to maintain high runtime integrity and automatically recover from indiscriminate damages, preserving global goal orientation and situation awareness in unpredictable and hostile environments.

the multiple robot coordination strategies have several advantages when compared to strategies based on a single robot, in terms of flexibility, gain of information and reduction of map building time. In this paper, a local pheromone map integration method is proposed based on the inter-robot observations, considering a method for the environment exploration named the Inverse Ant System-Based Surveillance System strategy (IAS-SS). Simulation results show that the map integration method is efficient, the trials are performed considering a variable number of robots in an indoor environment. Results obtained from several experiments confirm that the integration process is effective and suitable to execute the control of the access to pheromones in a virtual way.

this paper deals with a modeling approach for mode handling of Flexible Manufacturing systems (FMS). We show that using the plant model enables to establish aggregate operations. these are generic entities which depend only on the plant and do not depend on production goals. Aggregate operations are then used to build the model dedicated to mode handling. this study is illustrated through an example of a flexible manufacturing cell.

Event sequences estimation is an important issue for fault diagnosis of DES, so far as fault events cannot be directly measured. this work is about event sequences estimation with Petri net models. Events are assumed to be represented with transitions and firing sequences are estimated from measurements of the marking variation. Estimation with and without measurement errors are discussed in n - dimensional vector space over alphabet Z(3) = {-1, 0, 1}. Sufficient conditions and estimation algorithms are provided. Performance is evaluated and the efficiency of the approach is illustrated on two examples from manufacturing engineering.
Mobile robots are becoming increasingly prevalent in a large variety of applications. the introduction of robots into more complex environments necessitates the development of more advanced sensor systems to facilitat...

this paper analyzes the comfort of wheelchair users when a sliding-mode trajectory-tracking controller is used. the transmission of the horizontal (fore-and-aft) vibration to the head-neck complex (HNC) in the seated human body may cause unacceptable discomfort and motion sickness. A double-inverted pendulum model with two degrees of freedom is considered as a model for the HNC. the user comfort is examined not only in the time domain (using the fourth power vibration dose value), but also in the frequency domain (using the cross-spectral density method). For measuring the acceleration of the wheelchair, along the trajectory, an inertial measurement unit was used.

In this paper, a sliding mode control scheme is developed for a class of complex nonlinear systems withtheir T-S fuzzy models. It is shown that a set of extreme fuzzy subsystems are first derived, and a constructive sliding mode control law is then developed to guarantee the stability of the closed-loop fuzzy system. Simulation results are presented in support of the proposed scheme.
Recent publications have shown that under some conditions linear time-invariant systems become strictly positive real with constant feedback. To expand the applicability of this result to nonstationary and nonlinear s...

the concept of digital materials at the boundary of electric circuits and miniature robotics is studied. the main objective is to develop an experimental framework for the automatic assembly of basic electric circuits from the elementary modules. the framework is demonstrated on tiny modules, so-called bits, which take advantage of magnetic actuation and connection, both electrically and mechanically. the concept has potential application in small-scale robotics, especially for modular reconfigurable and versatile insect-scale robots, which can be used as elementary parts of complex reconfigurable machines.
