    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»

    A new position and speed sensorless control approach is proposed for permanent magnet synchronous motor (PMSM) drives. The controller directly computes an error for the estimated rotor position and adjusts the speed according to this error. The derivation of the position error equation and an idea for eliminating the differential terms, are presented. The proposed approach is applied to a vector c... View full abstract»

    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»

    Digital computer simulation provides an important tool for the study of complex systems. When the complexity of the problem is too large to warrant an analytical solution, simulation is the only option to analyze system configurations or operational modes prior to their implementation in the field. Not all components in a complex system can be modelled in adequate detail in computer simulations: f... View full abstract»
