ALGORITHM FOR SEQUENTIAL OPTIMIZATION OF THE STAGE OF EXTENDING THE SPOKES OF A LARGE-SIZED TRANSFORMABLE REFLECTOR
Annotation
The process of spokes extension of a large-sized space-based reflector is considered with the account for compression oscillations. An improved mathematical model of the spokes extension is proposed, which includes mechanisms of the stop and the lock of longitudinal vibrations. The model makes it possible to explore the system vibrations at any point of the spoke during the simulation. An algorithm for sequential optimization of the control of automatic extension of antenna elements has been developed, which allows minimizing system oscillations and fulfilling terminal conditions with high accuracy. Results of numerical simulation are presented, showing the advantage of the proposed algorithm in comparison with classical control methods.
