Simulation of a integrated power/attitude control system with single axis double flywheels

The utilization of flywheels to integrated power and attitude control system (IPACS) in satellites to replace traditional chemical batteries and attitude control system have the benefits of increasing reliability, reducing overall weight and spacecraft size, cost. The experimental device of single axis attitude control and energy storage system with two counter rotating flywheels is designed, and the attitude control is decoupled from DC bus voltage. A computer simulation model of a flywheel energy storage and single axis attitude control system is described in this paper. The goal is to research on control method of energy storage and attitude control use flywheel system, resolve the couple problem between energy storage and attitude control, study the key technology and prepare for the test system. The simulation results demonstrate that it is possible to use two flywheels to simultaneously provide energy storage while regulating the platform attitude in a single axis.
