Research on an Automatic Leveling and Positioning Control System

Abstract

A high-precision horizontal platform is needed for many engineering and military devices. This paper presents an automatic control device which can adjust the horizontal degree and position of the platform supported by four legs automatically. The device is controlled by PLC and positioning module, with the functions of detecting virtual legs and limit protection. The close-loop structure of control system is designed and a unidirectional control algorithm is proposed. The experiment showed that the device can adjust the level of the platform to 0.5°in 3 min.
