Abstract
Flywheel energy storage technology is a new and efficient energy conversion and storage method. The high-speed rotating flywheel is used to store mechanical energy, and the energy conversion between the electrical energy and the mechanical energy is realized by the transducer device. In a long-life, high-precision, high-stability three-axis attitude-stabilized satellite, the flywheel is an important and essential execution component. The double flywheel satellite system refers to a three-axis attitude satellite system with two flywheels on each of the three axes. Due to the complexity of the three-axis two-way flywheel energy storage attitude control system, it is impossible to accurately establish a mathematical model, which brings a lot of inconvenience to satellite attitude control. In recent years, intelligent control theory has been widely used in complex systems and has shown quite good control effects. The energy storage attitude control dual-purpose flywheel will disturb the attitude control of the satellite during energy feedback. In this paper, fuzzy logic control is used and the fuzzy controller of the current distributor of the flywheel energy storage system in energy feedback is designed by using MATLAB fuzzy logic toolbox. The fuzzy logic controller does not depend on the mathematical model of the object, and has excellent robustness. It has a good effect on the attitude control of the flywheel energy storage satellite in the energy feedback state.
