Methodology for designing a microcontroller system flywheel rotor speed control for highly dynamic spacecraft

Abstract

Background. In modern scientific publications of foreign scientists, the concept of controlling an electromechanical engine-flywheel unit with high-precision feedback on the speed of rotation of the rotor introduced into it is described. Examples of the implementation of this concept in domestic spacecraft do not meet the modern qualitative requirements for the management of highly dynamic vehicles. The purpose of the study is to create a new spacecraft control system based on controlling the rotation speed of the rotor of the electromechanical engine block-flywheel. Materials and methods. Practical tests of a typical number of domestic flywheel engines have been carried out using signal modeling approaches of a complex of testing equipment developed in “VNIIEM Corporation” JC. Results. Based on the tests results, a new prototype of the flywheel engine was created, on the basis of which the main technical characteristics were obtained and the restrictive requirements for the orientation and stabilization of the spacecraft necessary to create a control function for the rotation speed of the rotor of the electromechanical block of the future control system were determined. Conclusions. The created spacecraft control system made it possible to find the optimal target function for controlling the rotation speed of the rotor of the electromechanical unit of the flywheel engine type, which provided an increase in the efficiency indicator for a particular indicator of the accuracy of working out the required speed by more than 12% compared with the presented domestic spacecraft.
