Abstract: A static and dynamic analysis is carried out for spherical hydrostatic bearings under conditions of incompressible flow. The usual static theory is shown to need the addition of quadratic loss ...

Abstract: The problems of coordinated rate control and position control of multidegree-of-freedom arms are treated together in this paper. A mathematical formulation is presented which allows real time ...

Abstract: A state space approach is taken to vehicle merging on high speed highways. The vehicles are assumed to be traveling in equal sized “slots” which move at the group velocity. At points where ...

Abstract: The research problems in automated assembly are discussed. They are broken down into ten problem areas. The major theoretical issues are described and examples of different approaches are cited ...

Abstract: Geometric and force equilibrium conditions for successfully mating rigid parts are presented. The action of the Remote Center Compliance is explained. Guidelines for choosing RCC parameters are ...

Abstract: The preview control problem is one in which a controller can use future as well as present and past information to determine the control. In the optimal discrete finite preview problem studied ...

Abstract: A manual preview tracking experiment and its results are presented. The preview drastically improves the tracking performance compared to zero-preview tracking. Optimal discrete finite preview ...

Abstract: This paper describes a modified predictive controller that has been interfaced with the robotic weld bead grinding system currently under development at The Charles Stark Draper Laboratory. The ...

Abstract: This paper presents a basic review and explanation of the predictive control, discusses the inherent problems with the integrating component of the predictive control, and recommends some initial ...
