    Synthesis of Control of Terminal Acceleration of Spatial Rotations

    Get PDF
    Among the problems of Adaptive Terminal Control, one of the most important is the problem of control of acceleration process of moving objects. Two cases are discussed: Control with arbitrary terminal acceleration and control with certain value of terminal acceleration. The control law functions are obtained and analysis of the both process is represented. The obtained results can be used for practical purposes to elaborate simple control algorithms.Terminal Control, Moving Objects, Boundary Problems, Adaptive Control, Reduction, Acceleration, Transient Process

    Modelling of Deceleration Process of Spatial Movements

    Solution of breaking problem of moving mechanical object is discussed. Five boundary values are used for the problem. Mathematical model of the process has been obtained. Also all dynamic functions and characteristics are represented. They shoe the accuracy of terminal positioning of deceleration.Terminal control, moving objects, boundary problems, adaptive control, reduction, acceleration, transient process, deceleration, positioning of deceleration

    Analysis and Synthesis of Terminal Control Reduction Problem

    One of the most important problems of terminal control reduction problem is considered and solved. On the base of spinor representation of spatial rotation group, the control law functions are obtained. A mathematical model of reduction process is constructed. The results can be used for practical purposes to elaborate simple control algorithms of spatial movement reduction process in many different fields.Terminal Control, Moving Objects, Boundary Problems, Adaptive Control, Reduction, Acceleration, Transient Process

    Schwarzschild Models for the Galaxy

    Schwarzschild's orbit-superposition technique is the most developed and well-tested method available for constraining the detailed mass distributions of equilibrium stellar systems. Here I provide a very short overview of the method and its existing implementations, and briefly discuss their viability as a tool for modeling the Galaxy using Gaia data.Comment: 2 pages; invited review at "Modelling the Galaxy in the era of Gaia", proceedings of Joint Discussion 5 at the XXVIIth IAU General Assembly (Rio de Janeiro, August 2009); James Binney, Ian F.

    Simulating Cohort Earnings for Australia.

    This paper describes a dynamic microsimulation model of cohort earnings developed to consider redistribution during the working-lifetime in Australia. Microsimulation models were first used for economic analysis by Orcutt (1957), and are now commonly employed to undertake policy analyses in many countries around the world.INCOME ; SIMULATION ; ECONOMIC MODELS
