Focused on the highaccuracy and fast leveling control of the multipistoncylinders actuated bearing platform system, a new strategy combining the multilevel adaptive control and dynamic control allocation was proposed to realize the accurate and fast leveling control of the platform and to maintain the platform’〖KG-*2〗s center of gravity, in which system’s uncertain eccentricity, unknown friction and internal leakage in cylinders and hydraulic oil’s slowly timevariant characteristic were considered synthetically. To deal with restrictions in cylinders’ output force and overactuated problems, the dynamic control allocation strategy with the power minimization and input constraints was utilized, and each cylinder’s force was properly allocated by the active set algorithm.A simulation study, conducted on a vehicleborn platform’s leveling system with the proposed control strategy, indicated that the designed controller could effectively accomplish the fast and highaccuracy leveling of the vehicleborn platform.The proposed leveling control strategy provides theoretical basis and engineering practice reference for solving multicylinders actuating bearing platform’s leveling problems.
