VLF-method of nonlinear dynamic investigations in designing of systems for stabilization of spacecrafts
Some results of development of qualitative methods based on vector Lyapunov functions for dynamic investigations in designing gyroscopic systems for stabilization of flexible spacecrafts are presented. Models with distributed parameters and finite-dimensional ones, which take account of various perturbations, errors in elements, signal quantization and uncertainties, are considered. Desired properties in modes of attitude control and stabilization of assigned motions are formalized as either practical stability or dissipativity, investigation of which includes computing quantitative estimates of stabilization precision and of other direct dynamic quality criteria. These estimates are used (as criteria and restrictions) in procedures of synthesis of control with a warranted quality. The methods have been implemented in the corresponding software and have been applied in computing a member of real attitude control systems of space telescopes and communication satellites.
