Abstract
The article discusses the issue of using optimal control algorithms to minimize bending vibrations of the spoke of a large-sized transformable reflector in the process of its deployment. This reduces transient time and improves the reliability and safety of the antenna deployment process. The creation of large-sized space-based systems is a current trend. Such systems allow solving a wide range of problems related to monitoring the Earth’s surface and space. At the same time, due to their size, the issue of structural defor-mation arises. A mathematical model is presented that describes the process of deployment the spokes taking into account transverse vibrations. Optimal control algorithms have been developed to minimize structural vibrations. For the stage of adjusting the radio-reflective net, an algorithm has been developed that minimizes energy costs. The results are confirmed by mathematical modeling and testing of algorithms on a laboratory unit. A method for adjusting a radio-reflective surface has been proposed, which makes it possible to reduce the number of actuators while maintaining the number of actuation points.
