The control law makes the system closed-loop stable, and the gain of the system for the disturbance input will be limited under a scheduled upper - bound.

Put the disturbance moments of typical astronaut's push-off act as the input datas of the control system simulation, and analyze the response of the attitude control system after disturbed.

Considering the influence of the input disturbance, a mathematical description of road surface irregularity is established, which is the model of integral white noise and inspire with sine wave.
