This paper discusses on control law of the micro-gravity experimental vehicle with a balloon. To attain the micro-gravity environment, it is necessary that the experiment sphere in the experiment module does not collide with inner shell of the vehicle. This is achieved by designing the control law with 16 gas-jet thrusters. The velocity during free fall is accelerated to a supersonic region by the end of experiment. The design of control law corresponding to the remarkable increase of dynamic pressure is required. The performances of actual thrusters have high non-linearity. This paper proposes a new control law of thruster to control the vehicle with high accuracy.
