    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.

    Under the assumption of weak joint elasticity, a singular perturbation argument is used to show that recent adaptive control results for rigid robots can be used to control flexible-joint robots provided a simple correction term is added to the control law to damp out the elastic oscillations at the joints. In this way, fundamental properties of rigid robot dynamics can be exploited to design adap... View full abstract»

    It is shown that a neural network can learn of its own accord to control a nonlinear dynamic system. An emulator, a multilayered neural network, learns to identify the system's dynamic characteristics. The controller, another multilayered neural network, next learns to control the emulator. The self-trained controller is then used to control the actual dynamic system. The learning process continue... View full abstract»

    For a number of years, two-axis Sawyer motors have been used as motive devices for flatbed plotters and wafer probers. These two applications are quite different in their requirements for motor dynamics, but both depend on the motor's high speed and good open-loop positioning capability, as well as on its almost unlimited life expectancy. The motors are now being applied to a variety of other moti... View full abstract»

    Word directed toward the development of a vision system for bin picking of rigid 3D objects is reported. Any such system must have components for sensing, feature extraction, modeling, and matching. A structured light system which attempts to deliver a rich 2/sup 1///sub 2/D representation of the scene is described. Surface patches are evident as connected sets of stripes whose 3D coordinates are ... View full abstract»

    The positioning of the controller zeros near the slow process poles though greatly improving the speed of response for a set-point change, can be detrimental to load rejection. This result is used to explain the heuristics used in the Ziegler-Nichols tuning formula for proportional-integral-derivative controllers and in the positioning of controller zeros in pole-placement controllers and phase-la...

    A mobile robot whose behavior is controlled by a structured hierarchical neural network and its learning algorithm is presented. The robot has four wheels and moves about freely with two motors. Twelve sensors are used to monitor internal conditions and environmental changes. These sensor signals are presented to the input layer of the network, and the output is used as motor control signals. The ... View full abstract»

    Recent research in the area of adaptive machine tool process control is described. The process control problem in metal-cutting operations is considered, and the problems of online tool wear estimation and adaptive process control are discussed. Research in these areas is then summarized, and some results from the research of the authors, including recent laboratory experiments, are presented. Two... View full abstract»
