    A description is given of two Stanford University courses of one-quarter (10 weeks) each, covering the material of digital control of dynamic systems, by the authors. The courses have neither homework nor exams but are based on laboratories using IBM PC computers with locally designed and constructed analog plants. Rather formal reports are also required covering the seven laboratories in the two ... View full abstract»

    The use of computers for classroom presentations, exercises, laboratory experiments, and in projects is discussed. Commercially available simulation and computer-aided control system design packages can be used in teaching together with real-time software and with special programs developed for specific purposes. These possibilities are illustrated by citing many examples of learning and teaching ... View full abstract»

    A theory and prototype of a neural controller called INFANT, which learns sensory-motor coordination from its own experience, is presented. INFANT adapts to unforeseen changes in the geometry of the physical motor system and to the location, orientation, shape, and size of objects. It can learn to accurately grasp an elongated object without any information about the geometry of the physical senso... View full abstract»

  • Learning to control an inverted pendulum using neural networks

    Publication Year: 1989, Page(s):31 - 37
    Cited by:  Papers (270)  |  Patents (2)
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (776 KB)

    An inverted pendulum is simulated as a control task with the goal of learning to balance the pendulum with no a priori knowledge of the dynamics. In contrast to other applications of neural networks to the inverted pendulum task, performance feedback is assumed to be unavailable on each step, appearing only as a failure signal when the pendulum falls or reaches the bounds of a horizontal track. To... View full abstract»

    A robot hand control system called GeSAM, which is under development at the University of Southern California, is described. The goal of the GeSAM architecture is to provide a generic robot hand controller that is based on a model of human prehensile function. It focuses on the relationship between geometric object primitives and the ways a hand can perform prehensile behaviors. It is shown how th... View full abstract»

    A type of neural network, the multilayer perceptron, is used to classify numeric data and assign appropriate symbols to various classes. This numeric-to-symbolic conversion results in a type of information extraction, which is similar to what is called data reduction in pattern recognition. The use of the neural network as a numeric-to-symbolic converter is introduced, its application in autonomou... View full abstract»

    The use of artificial neural networks for the management of sensory and motor trajectories is introduced. In the approach presented, the space-time functions representing the trajectories are separated so that the spatial parameters are stored in one neural map and the time parameters are stored in a second neural map. An approach called a neural triangular lattice is suggested for implementing th... View full abstract»

    The problem of automatic tuning of simple regulators is examined. The key idea is to design an aid for the process operator, which should use minimal prior information about the system. This is a typical example of a case where it is essential to develop techniques that will give crude but robust estimates. The development has resulted in a novel generation of the classical PID (proportional, inte... View full abstract»

    Consideration is given to the possibility of applying fuzzy algorithms in a microprocessor-based servomotor controller, which requires faster and more accurate response compared with other industrial processes. The performance of proportional-integral-derivative control, model reference adaptive control, and fuzzy controllers is compared in terms of steady-state error, settling time, and response ...

    Experience with the linear-quadratic-Gaussian/loop-transfer-recovery (LQG/LTR) design methodology has demonstrated several inadequacies in that theory of design. The author focuses on the problems associated with the selection of a state weighting matrix for the regulator design (or of the process noise covariance matrix for the filter design) to satisfy constraints on the singular values of the d...

  • An experiment demonstrating pointing control on a flexible structure

    An experiment called the jitter beam simulates the interaction of a pointing control system and a flexible structure. Noncolocation of a sensor and an actuator makes control difficult. A linear-quadratic-Gaussian design overcomes the noncolocation problem by use of a dynamic model that includes structural bending. The capability to deal with noncolocation enables the jitter-beam control to coordin... View full abstract»
