  • Natural tracking with a prediction-error based parameter estimator

    Publication Year: 1997, Page(s):80 - 86

    Current trends in control applications are oriented toward control algorithms which, to the least extent, depend on the system's mathematical model and/or its parameters. The recently disclosed concept of high gain natural tracking is one such approach to control of nonlinear dynamic systems. This law is independent of the plant's internal dynamics, but dependent on the system parameters. The work... View full abstract»

  • Robust detection and isolation of process faults using neural networks

    Publication Year: 1997, Page(s):72 - 79

    The problem of robust model-based diagnosis of process faults is addressed by means of artificial neural networks. Different structures and learning methods are investigated for both approaches to function approximation and pattern recognition. Main emphasis is placed upon static and dynamic neural nets that are used as predictors of nonlinear models for symptom generation. Dynamic neural networks... View full abstract»

  • A new matrix model for discrete event systems: application to simulation

    Simulation schemes for discrete event (DE) systems based on a new DE matrix formulation are presented. This new formulation is a hybrid system with logical and algebraic components that allows fast, direct design and reconfiguration of rule-based controllers for manufacturing systems. It applies to general DE systems that include shared resources, dispatching, circular waits, and variable part rou... View full abstract»

  • Identifying chaotic systems via a Wiener-type cascade model

    Publication Year: 1997, Page(s):29 - 36

    In this article we first show a theory that the Wiener-type cascade dynamical model, in which a simple linear plant is used as the dynamic subsystem and a three-layer feedforward artificial neural network is employed as the nonlinear static subsystem, can uniformly approximate a continuous trajectory of a general nonlinear dynamical system with arbitrarily high precision on a compact time domain. ...

  • Benchmarks for the numerical solution of algebraic Riccati equations

    Publication Year: 1997, Page(s):18 - 28

    Two collections of benchmark examples are presented for the numerical solution of continuous-time and discrete-time algebraic Riccati equations. These collections may serve for testing purposes in the construction of new numerical methods, but may also be used as a reference set for the comparison of methods View full abstract»

  • Multiobjective H2/H guaranteed cost PID design

    Publication Year: 1997, Page(s):37 - 47
    Cited by:  Papers (39)

    This article presents a methodology for sub-optimal design of PID compensators for systems subject to disturbance signals and to parametric uncertainties of polytope type. The adopted optimality criteria are the H2 and H norms of the transfer matrices from the disturbance inputs and from the reference input to the controlled output error. Time constant constraints are ... View full abstract»

  • Algorithms and software for LMI problems in control

    Publication Year: 1997, Page(s):89 - 95
    Cited by:  Papers (29)
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (816 KB)

    A number of important problems from system and control theory can be numerically solved by reformulating them as convex optimization problems with linear matrix inequality (LMI) constraints. While numerous articles have appeared cataloging applications of LMIs to control system analysis and design, there have been few publications in the control literature describing the numerical solution of thes...

    In this article, we describe and develop methodologies for modeling and transferring human control strategy. This research has potential application in a variety of areas such as the intelligent vehicle highway system, human-machine interfacing, real-time training, space telerobotics, and agile manufacturing. We specifically address the following issues: (1) how to efficiently model human control ... View full abstract»
