Abstract: |
In order to demonstrate that it is possible to use two reverse rotating flywheels to simultaneously provide energy storage and attitude control in a single axis, a kind of integrated energy storage and attitude control system composed of bias momentum wheels was researched by theory analysis and simulation. Based on the experimental system and its characters in energy storage and release process, the system models during the energy storage and release were obtained and their corresponding control algorithms were given. In the energy storage and release process of the system, the angle regulation of air table and the speed variable of double flywheels were simulated on the Matlab/Simulink platform respectively. The simulation results show that the energy storage and release could be realized with double flywheels during the angle regulation, which verifies the feasibility and effectiveness of the control scheme, and provides the theory and design basis for further research. |
