Investigation of an approximate model of a big space structure for analyzing the dynamics of its orientation control system with the help of digital simulation
Abstract:
The paper examines the process of computation errors accumulation in the integration of modes and envelopes equations in the approximate model of a big space structure motion. The equations describing these errors as functions of the integration steps number and step size under an arbitrary control law. Digital simulation is applied for investigating the errors change dynamics for a specific object, and the recommendations on integration step selection ensuring admissible error values are made.
