DIGITAL AND PULSE-WIDTH CONTROL OF A SPACE ROBOT WHEN APPROACHING A GEOSTATIONARY SATELLITE

摘要

The control problems on a space robot during its approach to an information geostationary satellite are considered. The robot motion control system uses an electric propulsion system with 8 engines at the pulse-width modulation of their thrust values and a gyroscopic moment cluster based on 4 gyrodines with digital control. Numerical results are presented that demonstrate the effectiveness of the developed discrete guidance and control algorithms.
