Multi-supporting leveling platform was wildly applied in areas of normal or military industry. To complete some frocking targets, it usually requires good performance of levelness and short time adjustment. It is very meaningful to enhance the automatic level of leveling platform by mining adaptive controlling algorithm which satisfied the levelling error and used shorter time. In this paper, four-point supporting electromechanical leveling system was set as the object to study. By analyzing the leveling characteristic of the system, appropriate leveling strategies were put forward. The simulation result of the system, whose model was built based on MPC, show that this way achieves good auto leveling performance.
