Design of Automatic Leveling Control System for Special Vehicle-mounted Platform

Special vehicles often need to keep the body level quickly and accurately when carrying out follow-up control or missile launch. In order to enhance the mobility of the special vehicle during the leveling process, this paper takes the special vehicle as the research object and designs a set of automatic leveling control system. On the basis of hydraulic drive, the automatic leveling system is designed with a compact mobile vehicle controller as the core. The information is transmitted between the modules of the system through the CAN bus, combined with the existing leveling strategy, a leveling strategy combining the angle error control leveling method and the pursuit of the highest support point leveling method is adopted. The test results show that the leveling system has the characteristics of short leveling time, strong stability and high reliability, the leveling accuracy reaches $3\prime$, and the leveling time is within 30s.
