Abstract
Possible approaches to the mathematical description of different types of flexible vehicles in view of structural oscillations, oscillations of fluid in tanks and moving masses inside the vehicle are observed. Elastic bending of a body surface in interaction with a surrounding medium in a broad band of speed variation are taken into account. Problems of regulator's synthesis and effective damping of elastic oscillations are solved for nonstationary flexible controlled plant. In the process of regulator's synthesis the local aerodynamic effects, dynamics and metering errors of sensors, time lag of engines and other elements of control system are considered. Methods of varying eigenfrequencies estimation in the real time are used for the control quality increasing. Principles of universal software design were developed for solving these complex problems of dynamic properties research, simulations of elastic vehicles motion and synthesis of perfect control law. Functioning of the program package is demonstrated and outcomes of calculations are presented.
