The attitude control of extra-vehicular activity (EVA) is a nonlinear and time variant control system with the uncertain parameters. It is difficult for general control method to deal with attitude control of EVA. For validating the disposal of adaptive control method for the problem and engineering practicability of this method, a half-physical simulated system based on DSPACE environment was established. This system ould simulate reality environment and gave out reliable result. Consequently it show that adaptive control method is of good control quality for EVA.
