    This paper discusses the background of the new Boeing 7J7 airplane that currently is in the preliminary design phase. The advanced technologies under development for application to this 150-passenger, short-to-medium-range airplane design are described, together with their impact on the operational costs of the airplane. Specific areas of interest include the ultrahigh-bypass engines, advanced str... View full abstract»

    Historical highlights and a progress review of sampled-data systems are presented herein. Recent emergence of digital signal processing and digital filters as an aftermath of sampled-data systems is brought into focus as well as the technological developments that aided in this new emergence. Recent advances made in multidimensional discrete theory and its applications are also discussed. The pape... View full abstract»

  • Space structure vibration modes: How many exist? Which ones are important?

    Publication Year: 1987, Page(s):22 - 28

    This paper attempts to shed some light on the two issues raised in the title: How many vibration modes does a real structure have? and Which of these modes are important? The author argues that the "absurd subspace" (all but the first billion modes) is not a strength of continuum modeling, but, in fact, a weakness. Partial differential equations are not real structures, only mathematical models. T... View full abstract»

  • Adaptive control for the space station

    Publication Year: 1987, Page(s):29 - 34
    Cited by:  Papers (13)

    This paper describes an adaptive control algorithm along with the proposed inner-loop plant augmentation for controlling the space station under severe conditions of shuttle docking, mass and inertia change, and model truncation. Simulation results with a simplified model show that the controller is robust and the plant dynamics closely follows that of the reference model. Reasonable results have ... View full abstract»

  • Maximum likelihood using an array processor

    Publication Year: 1987, Page(s):35 - 38

    Maximum likelihood estimation (MLE) is a method used to calculate the parameters of a dynamic system. It can be applied to a large class of problems and has good statistical properties. The main disadvantage of the MLE method is the amount of computation required. This paper describes how the computation time can be reduced significantly by using an array processor. The estimation of the parameter... View full abstract»

    A simple feedforward adaptive scheme is applied for temperature control of a heated airstream. The system exhibits different thermal time constants for heating and cooling and nonlinear static characteristics. The control scheme consists of a fixed regulator, to which an adaptive feedforward signal is added to improve tracking transients. Adaptation acts only during reference changes, and its effe...

    This paper describes the Computer Integrated Manufacturing Systems (CIMS) Program at the Georgia Institute of Technology, which was established with the help of a grant from the IBM Corporation. The program began its third year recently and involves a cooperative effort among eight schools (departments) within Georgia Tech, with strong support and interaction with over a dozen industries. The prog... View full abstract»

    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (380 KB)

    The modeling, analysis, and design of a ball-balancing control system are considered. An optimal linear regulator control system is constructed, and an optimal hybrid controller capable of absorbing external disturbance is implemented. The controller design is based on the theory of disturbance-accommodating control, optimal linear quadratic regulator control, and a digital delayed-data observer. ... View full abstract»

    The design of lightweight links for robotic manipulators results in flexible links. Accurate control of lightweight manipulators during the large changes in configuration common to robotic tasks requires dynamic models that describe both the rigid-body motions, as well as the flexural vibrations. This paper describes a linear state-space model for a single-link flexible manipulator and compares si... View full abstract»

    The results of an experiment for controlling two robot arms in a cooperative manner are presented. The purpose is to move an object by grasping it at two different points using two separate robot arms. Once a path of the object is determined, the differential increments of the Cartesian trajectories of the two robot hands are obtained from the differential increments of the object. Then, the corre... View full abstract»

    This paper presents the design and analysis of a drive system to soft couple the solar dynamic power systems from interaction with the structure of a single-keel space station. The drive system features a low-bandwidth controller that attenuates the dominant transverse boom torsional mode. In addition, minimizing the effects of induced force disturbances on pointing is essential in achieving desir... View full abstract»
