    The control of complex dynamic systems is one of the major tasks of modern control theory. The high dimensionality of complex systems often requires decentralized control concepts. In computer science, multiagent systems are proposed for use in distributed intelligent applications. To solve the common task, the single agents have to communicate and to interact in a suitable way. In the case of a r... View full abstract»

    Meta-programming a multi-agent system is a complex task due to the fact that as the agents build their strategies the environment changes. We propose a method and a language for multi-agent meta-programming based on explanation based learning and we unify these ideas under a formal framework. As an example, we report our experience of use of our meta-programming method on the example of predators ... View full abstract»

    A variety of mobile robot tasks require complete coverage of an initially unknown environment, either as the entire task or as a way to generate a complete map for use during further missions. This is a problem known as sensor-based coverage, in which the robot's sensing is used to plan a path that reaches every point in the environment. A new algorithm, CCR, is presented here which wor...

    To guarantee a constant quality of manufactured products, it is necessary to optimize the process parameters immediately when a failure of the workpiece quality has been observed. Since this relationship of measurement and process parameters is complex and nonlinear in most cases, this feedback loop is closed manually by an experienced operator in general. In the paper the concept of a fuzzy model... View full abstract»

    The paper presents a robust fault diagnosis scheme for detecting and accommodating faults occurring in a class of nonlinear multi-input multi-output dynamical systems. Changes in the system dynamics due to a fault are modeled as nonlinear functions of the control input and state variables. The fault function can model slowly developing (incipient) or abrupt faults, with each component of the fault... View full abstract»

    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (472 KB)

    Emotions and rationality have often been treated as opponents, with emotions taking on the role of villain and rationality taking on the role of heroine. Recently, however, the positive role of emotions has received considerable attention, and resulted in the elevation of emotion to rationality's equal. With emotion's change of status, artificial and computational intelligence researchers have beg... View full abstract»

    The behavior of manufacturing systems with discrete I/O signals can be characterized by the timing and sequencing of changes (events) in these I/O. In this paper, we present a method to monitor these signals to alarm when faulty sequencing or timing behavior occurs, and also to warn when the timing starts to deviate from its normal behavior. This is accomplished by using a combination of the time ... View full abstract»

    There are many situations, in engineering and economic systems, where several decision makers (DMs), sharing different information patterns, cooperate to the accomplishment of a common goal. We address an approximate technique consisting in constraining the control functions to have a fixed structure (we chose feedforward neural networks). We are then able to obtain solutions that approximate the ... View full abstract»

    This document introduces the concept of type-2 fuzzy sets and compares the type-2 fuzzy set preliminaries with the ordinary type-1 fuzzy set. Two theorems are proved: the first one helps to generate the general form of the type-2 operations, the second provides an approach to transfer the type-1 fuzzy uncertainties to the type-2 system View full abstract»

    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (440 KB)

    One of the main problems of fuzzy control is that the number of rules which are necessary to represent a given control strategy with a given accuracy, grows exponentially with the increase in accuracy. As a result, for reasonable accuracy and a reasonable number of input variables, a great number of rules is sometimes needed. In this paper, we start to solve this problem by pointing out that tradi... View full abstract»
