    Some key ideas about the use of fuzzy models in predictive control are presented. The discussion is extended to the use of interior point methods to solve the optimization problem in predictive control problems. The use of interior point methods opens the door to the formulation of robust optimization problems and by using this formulation a robust model predictive control strategy can be formulat...

    Predictive control was first developed to control linear time invariant plants described by ARIMAX models. The extension of this control strategy to the case when the behavior of the plant is nonlinear and modeled by a Takagi-Sugeno fuzzy model is considered. This kind of nonlinear model is locally linear and the GPC technique can be extended as a parallel distributed controller View full abstract»

    Pipeline surface defects such as cracks cause major problems for asset managers, particularly when the pipe is buried under the ground. The manual inspection of surface defects in the underground pipes has a number of drawbacks, including subjectivity, varying standards, and high costs. Automatic inspection systems using image processing and artificial intelligence techniques can overcome many of ... View full abstract»

    Efficiency is a major concern for all problem solving systems. One way of achieving efficiency in multi-agent systems is the application of cooperation techniques to speed up problem solving. Coalition formation can improve the performances of a multi-agent system by solving problems collectively. Given the different work done on coalition formation, unfortunately, many approaches present several ... View full abstract»

    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»

    Presents a genetic based control structure for active control. The proposed active control structure has an adaptive system whose controller is an infinite impulse response (IIR) filter and the adaptive mechanism is a genetic algorithm. Adaptive filtering schemes based on a genetic algorithm have been studied, but their application is limited to the system that is able to know desired signals dire... View full abstract»

    We consider the centralized, decentralized and overlapping approaches to designing controllers for shape control of a segmented telescope. In each case, we design controllers using the H∞ robust control approach. In the centralized control case, the disturbances are rejected over a wide frequency range and all performance requirements are met. The order of the centralized control... View full abstract»

    The discussion of intelligent system usually starts with issues of defining intelligence as a set of skills, but always ends with specifying the mechanisms of learning. It is important to address the issue of differences and similarities between the techniques of computational/control learning processes (very similar to the processes of semiosis) and biological learning including evolution of spec...

    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...

  • Theoretical aspects of multiresolutional autonomy

    Publication Year: 1999, Page(s):370 - 374

    The phenomenon of autonomy is equivalent to assigning and producing a system of complicated goals that frequently form a multiresolutional hierarchy stemming from the concept of survival. Thus, autonomy of a system dwells upon the multiresolutional (multigranular, multiscale) world representation within the intelligent system and upon the associated computational mechanisms that enable the existen...

    Discusses two problems in the decentralized adaptive control of the outputs of a discrete-time dynamical system using multiple controllers, when each controller has only partial information concerning the overall system. The first problem is one of achieving exact tracking when the controllers communicate to each other their control decisions but not their measured system outputs. The second probl...

    It is known that modular synthesis for discrete event systems can render better design flexibility than centralized synthesis. This paper extends the author's previous centralized method (1997) to a new method for modular supervision of timed discrete event systems (TDES). Control problems are expressed in terms of forbidden conditions on the base state space of TDES. For tackling such control pro... View full abstract»

    Thorough testing of a huge aerospace structures results in a large amount of data, and long processing time. To decrease the processing time, we use a “multi-resolution” technique, in which we first separate the data into data corresponding to different vibration modes, and then combine these data together. We show how a general methodology for choosing the optimal uncertainty represen... View full abstract»

    We have developed a novel, general technique involving nonlinear transformation that summarizes the four hundred and two amino acid properties contained in the Nakai database in the form of two simply visualizable indices. The technique yields a higher fidelity of representation of the original data than linear methods, and results in a distribution of the amino acids which illustrates their depen...
