Abstract

The general structure and working principle of the single axis energy storage/attitude control system were introduced. The mathematical model of the system was studied and put forward; the cause of errors was analyzed; the equations of platform angular error and flywheel install error

the platform angle error and flywheel eccentricity error

the platform angle error and error of flywheel speed measurement and control were also analyzed

respectively; then every piece of errors were compounded. The actual errors were computed combined with the actual experimental system

and each error was compared and analyzed. The results show that the primary factors are the flywheel install error

flywheel eccentricity error

speed measurement error and control error etc. The install error and eccentricity error are uncontrolled factors

while the flywheel speed measurement error and control error are controllable factors. In conclusion

the primary method that can improve the attitude control precision is presented; the speed measurement error and control error of flywheels can be reduced by improving the resolutions of position sensor and speed sensor

as well as adopting advanced control algorithm.
