Planetary surface is covered by soft soil. Thus wheel slips and gets stuck easily. Wheel slippage causes wheel stuck, navigation error, and difficulty in climbing slopes. Purpose of this research is to develop wheel control system for efficient travelling on soft soil. The efficient travelling is that a rover is able to travel on high speed and small wheel slippage on soft soil. Considering strong control system for disturbance, it is important to incorporate terramechanics theory. In this paper, wheel dynamics model based on terramechanics is proposed, and the dynamics model is verified it is appropriate for dynamic motion by simulation analysis.
