An overshoot-free high-precision multi-point hydraulic platform leveling algorithm for heavy-load AGV

With the rapid development of artificial intelligence technology, the intelligent manufacturing and logistics transportation industries are undergoing profound changes. The rise of China's manufacturing industry has further intensified the growth in demand for the transportation of large and heavy objects. Traditional transportation methods such as cranes, manned freight, rail cars, etc. are no longer able to meet the growing demand and safety requirements. Therefore, heavy-duty Automated Guided Vehicle(AGV) emerged as the times require. Our company has successfully manufactured an Automated Guided Vehicle(AGV) with a load capacity of 360 tons and put it into actual use. In order to solve the problem of load stability of heavy-duty Automated Guided Vehicle(AGV) on complex roads, this paper designs an automatic leveling control system based on a multi-point hydraulic platform and constructs the transfer function of the system. Through simulation verification, the fusion of the highest-point leveling strategy and the fuzzy PID algorithm proposed in this article perform well in the leveling control of heavy-load Automated Guided Vehicle(AGV). Compared with the traditional algorithm, there is no overshoot phenomenon, high stability, and can be achieved within 2.5 seconds. Reach a steady state with smaller steady-state error.
