    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.

    This paper presents an approach to the automatic redesign of flight control systems for aircraft that have suffered one or more control element failures. The procedure is based on linear quadratic (LQ) design techniques, and produces a control system that maximizes a measure of feedback system performance subject to a bandwidth constraint.

    A comparison is made of a neural-network-based controller similar to the cerebellar model articulation controller (CMAC) and two traditional adaptive controllers, a self-tuning regulator (STR) and a Lyapunov-based model reference adaptive controller (MRAC). The three systems are compared conceptually and through simulation studies on the same low-order control problem. Results are obtained for the... View full abstract»

    A microrobot having two high-performance parallel drive limbs which has been developed for manipulation, surgery, and dynamic mechanical testing of very small objects such as single living cells is described. The end points of each limb move in overlapping spherical workspaces of 1-mm diameter with minimum open- and closed-loop movements of 1 nm and 10 nm, respectively. The displacement bandwidth ...

    A short introduction to the control aspects of therapeutic drug delivery is presented. Intrinsic feedback control mechanisms that occur in most therapeutic situations are discussed. The application of control engineering methods in open-loop drug delivery, which uses mathematical models of the dose-effect relationship of the drugs, together with parameters identified from population statistics, is...

    Certain continuous-time self-tuning algorithms are shown to be capable of generating tuning parameters for commercial proportional-integral-derivative (PID) controllers. They are also shown to be capable of generating a feedforward signal that decouples the disturbance from the interaction from adjacent loops in a multivariable situation. The approach is verified using a standard Atari personal co... View full abstract»

    The W. M. Keck Observatory and Telescope are presently under construction on Mauna Kea, Hawaii. When completed in 1990, the telescope will be the world's largest instrument for astronomical observations at visible and infrared wavelengths. The primary mirror has a diameter of 10 m and consists of a mosaic of 36 hexagonal segments, with the orientation of each segment actively controlled. This pape... View full abstract»
