Nonlinear Dynamic Research of the Spacecraft Robust Fault Tolerant Control Systems

Abstract

New results on methods and software for nonlinear dynamic research and design of robust gyromoment fault tolerant control systems by the information spacecraft (remote sensing, communication, navigation and geodesic) developed by the leading Russian State Space Research and Production Associations (RPAs) -the TsSKB-Progress and the NPO PM , are presented.

Methods for attitude guidance and precise robust gyromoment control of large-scale agile observation spacecraft

“…Standard Newton iteration method was applied for numerical obtaining a strict optimal "control" v(t), moreover analytical solution (initial point) was applied in the form of approximate optimal motion (11). Difference between approximate optimal motion and strict optimal motion is very light for the SC practical rotational maneuvers.…”

“…Increased requirements to such information satellites (lifetime up to 10 years, exactness of spatial rotation maneuvers with effective damping the SC flexible structure oscillations, robustness, fault-tolerance as well as to reasonable mass, size and energy characteristics) have motivated intensive development the gyro moment clusters (GMCs) based on excessive number of gyrodines (GDs) -single-gimbal control moment gyros. Mathematical aspects of the SC nonlinear gyromoment control were represented in a number of research works [1,2] et al including the authors' papers [3][4][5][6][7][8][9][10][11][12][13][14][15][16][17][18]. The paper suggests new results on attitude guidance and nonlinear robust gyromoment attitude control of the agile observation spacecraft.…”
