Theory and Software for Simulation of Complex Flexible Aerospace Vehicles and Smart Control

The concept of a universal program for research into dynamic properties, calculation of comprehensive mathematical models, simulation of the flight motion and synthesis of smart control laws for different types of the flexible aerospace constructions (launchers and missiles) is considered. The basis of the program is the structure, which allows carrying out of the analysis of dynamic characteristics, simulation, and visual information representation. The software package is supplied with the library of program modules. These modules are designed on the base of mathematical models of separate vehicle elements and different physical effects, such as flexibility, sloshing, sluggishness of engines, local angle of attack values, etc. Selection of different sets of the mathematical models and program modules allows investigating different constructions for known and prospective vehicles. The interface of the program enables changing parameters of the vehicle in a wide range, to simulate flight at any trajectory and to output results of the analysis in a digital or graphical form. For synthesis of control laws, provides the usage of the smart control approach.
