Instruments and Systems: Monitoring, Control, and Diagnostics Annotation << Back Digital control of landing flight vehicle D.B. ROZHDESTVENSKIY The technology of landing flight vehicle along the previously calculated reference trajectory is examined. The procedure of calculation of controlling influence with landing of flight vehicle is represented. By the special feature of procedure in comparison with the contemporary methods of automatic landing is the use of prediction algorithms and calculation the derivative of process. The method of extrapolation used is based on the suppression of the known phenomenon of Gibbs, which appears with any method of the approximation of discontinuous functions. The approximation method of discontinuous functions is based on the conversion, which changes the spectrum of the approximated discrete sequence, as a result of which for obtaining the approximating function it is possible to use a method of amplitude demodulation. For obtaining the algorithm of extrapolation forecastability conditions are formulated. The application of an algorithm of extrapolation makes it possible to obtain the function of disagreement at the future position of reference trajectory. Is examined the method of molding of controlling influence on the basis of obtaining at the future position of the value of disagreement, which is been the function of the difference between the reference and real trajectories and the values of derivatives of reference and real trajectories at the same point. This method of control improves stability and accuracy of control, which makes it possible to compete with the methods of robust stability and robust control, by those by widely utilized in the theory of control. In the article the technology of high-precision control of mobile object for the case of achieving the fixed (stationary) purposeful point is examined. The basic condition, utilized with the solution of this stationary problem, can be used, also, for the nonstationary point, for example, for the case of landing on the aircraft-carrying ships. The program set based on system Delphi is developed for the analysis of properties and characteristics of control system for landing of flight vehicle.
