摘要
调平是重载平台应用中的一项关键技术,文章设计了重载平台的调平方案,分析了最高点不动的"追逐式"调平法的原理。针对调平过程的控制难点,将PID与模糊控制相结合,采用模糊自适应PID控制器控制调平过程。运用AMESim和Simulink建立了重载平台调平的模型,完成了调平过程的联合仿真。仿真结果表明:最高点不动的"追逐式"调平法适合于重载平台调平,模糊自适应PID控制器的精度高。
Leveling is a critical technology in heavy load platform application. Leveling scheme is designed for heavy load platform and the principle is analyzed about the highest point not moving ＂chasing style＂ leveling method. PID and fuzzy control are connected in view of the difficulty in leveling control process. Fuzzy adaptive PID controller is employed in leveling control process. The leveling model of heavy load platform is established with AMESim and Simulink. United simulation of leveling process is completed. Simulation results demonstrate that the highest point not moving ＂chasing style＂ leveling method is suitable for heavy load platform leveling. Fuzzy adaptive PID controller has high precision.
