Control strategy of three-point supported automatic levelling platform

Based on three-point supported automatic leveling platform, this paper first establishes the mathematical model of leveling platform, and determines the kinematic relationship between front&rear pitching, left&right lifting and its supporting leg action, then tests and analyzes different leveling control methods on the platform through the experiment, finally explores the coordinated control strategy of signal acquisition system and platform support leg servo system and leveling control system according to the test data, and presents flow chart of the control strategy in the working process of the automatic leveling platform. The control strategy can guarantee the fast response of the automatic leveling platform during the leveling process.
