    There are two general structures to design a control system through a network. The first structure is to have several subsystems, in which each of the subsystem contains a set of sensors, a set of actuators, and a controller by itself. These system components are attached to the same control plant. In this case, a subsystem controller receives a set point from the central controller. Another struc... View full abstract»

    Monitoring a factory remotely over the Internet introduces a variety of issues: how to capture the factory's data in a Web-accessible database, locate the data from anywhere in the world, display it locally using a Web browser, protect private data during transmission, and shield it from unauthorized viewing. Solving those problems from scratch would be difficult, but fortunately that is not neces... View full abstract»

    The design of advanced controllers for many industrial processes is heavily dependent on the availability of a model for the process. Construction of appropriate models is often not possible due to the complexity and nonlinearity of the process. Fuzzy logic can be used for different tasks within intelligent control systems because they represent general, nonlinear relationships that can be initial... View full abstract»

    One of the amazing successes of biological systems is the ability of animals to learn to control the complicated dynamics of their muscles and joints smoothly and efficiently. Traditional engineering control techniques, on the other hand, often do not perform well when confronted with intrinsically complex systems with many degrees of freedom such as a robot arm (human arm).

    In this paper we develop a method using temporally abstract actions to solve Markov decision processes. The basic idea of our method is to define some kind of procedures to control the agent's behavior. These procedures contain a rule constraining actions the agent has to choose. This rule is applied except if some conditions (which we call exceptions) are fulfilled. In this case we relax constrai... View full abstract»

    The use of cage-rotor three-phase induction generator (IG) presents considerable advantages mainly due to its robustness and low cost. However, the low performance in terms of voltage and frequency stabilization is an important drawback when trying to guarantee power quality to the load. This paper contributes in presenting an IG-basic structure which employs power-electronic converters associated... View full abstract»

    A new fault management protocol that makes use of native fault tolerant features of TTP/C has been developed. It can tolerate multiple node failures no matter how close in time and in minimum time. The time it takes to detect a node failure and to reconfigure the system is minimum and it is fixed by the TTP/C protocol. The protocol tolerates the fact that several nodes, including the active manage... View full abstract»

    In electric vehicle (EV) applications efficient consumption of energy is very important. Also there is so far no universal agreement in regard to which motor should be used. Different motors like DC motor, induction motor, permanent magnet motor etc. have been put into operation. The induction motors, although rugged and less expensive, have the problems of low efficiency at lower load. This paper... View full abstract»

    Co-generation systems integrating distributed low-power sources with the utility generally ask for an electronic power converter for conditioning the locally generated power and inject current into the grid. If the source provides a DC voltage, the converter should be able to produce a low-distortion, high-power factor AC current. For low-power applications, like photovoltaic panels and fuel cells...

    This paper proposes a new sliding-mode direct torque control (DTC) for an induction motor. This DTC is established by designing two sliding surfaces for the torque and the flux. The authors propose a novel sliding surface for the torque, which is based on the integral-sliding surface, whereas the sliding surface for the flux follows that of Benchaib et al. (1999). They also modify the flux observe... View full abstract»

    In real control systems, there are some constraints on the value of inputs, states and outputs. If such constraints are violated, systems may become unstable as the worst case scenario. One of the promising approaches to solve this problem is to switch the controller according to the state of the closed loop system. No useful design strategy for each controller, however, has been developed yet. In... View full abstract»

    In many studies, biped robots are controlled on the assumption that friction between the floor and the feet of the biped robot is large enough. This assumption is necessary for biped robots, because slipping of biped robots never happens on such a floor. But in a real environment, it is not necessarily true that all floors on which biped robot walks have enough friction. For the practical use of a... View full abstract»

    To improve the performance of a conventional PI-controller based linear permanent magnet synchronous motor (LPMSM) drive, this paper applies a fuzzy logic scheme for on-line tuning the PI controller parameters. The proposed method can be easily implemented, since it is based on the existing LPMSM control framework and does not require intensive computation, and is thus more appealing to current in...
