An electrostatic positioning system for material processing has been developed and tested under the microgravity environment in the MU-300 aircraft. Total of 36 parabolic flights have been performed to obtain the positioning characteristics of the system depending on samples, feedback gains, and control rules. The control system is equipped with a fuzzy reasoning processor and three types of the membership functions and the control rules are tested in the experiment. The experimental results show the position error of the sample is about 2 mm and is restricted by the feedback gain in the vertical direction. However, in the horizontal direction, the position error becomes as large as 10 mm depending on the g-levels of the aircraft. The acceleration levels of the sample strongly depend on the fuzzy reasoning parameters and they are less than the g-levels of the aircraft when the adequate control reasoning was selected for the feedback control. A tracking simulation is performed using measured g-levels of the aircraft. The results of the positioning give good agreement with the experimental results.
