三峡升船机承船厢的自动调平系统是一个多通道的开关式电磁阀控制的位置控制系统，是三峡升船机研制中的一个关键问题。本文分析了三峡升船机的特点，针对这些特点提出了模糊控制策略，设计了微机控制系统，并在模型上进行了试验研究，试验结果十分令人满意。 The automatic leveling system of the ship lift of the Three Gorges ship lift is a key position control system developed by the multi-channel switch-type solenoid valve and is a key issue in the development of the Three Gorges ship lift. In this paper, the characteristics of Three Gorges ship-lift ship are analyzed. According to these characteristics, the fuzzy control strategy is put forward. The microcomputer control system is designed and tested on the model. The test results are very satisfactory.
