Intelligent Approach to Experimental Estimation of Flexible Aerospace Vehicle Parameters

AbstractThe model used for the design of control systems for elastic aerospace vehicles is characterized by certain set of parameters depending on elasticity of the construction. These parameters change in the course of flight and differ for each copy of the object. The estimation of these parameters is carried out at a design stage of the object construction with use of special software using the finite elements method. More exact results of natural experiment turn out during bench tests with a mock-up model or finished object. The final estimation of parameters of elastic object indirectly is accomplished in the course of flight with use of means of the adaptive control and the optimum estimation of the state-space vector, when elastic properties of object are linked indissolubly with aeroservoelasticity. The proposed approach is based on use of special features of construction of the simplified models of elasticity and methods of identification of its elastic properties can be used at each stage.
