Coupling Leveling Control Based on Fuzzy PID for Synchronous Loading System of Load-Bearing Test Bed

This paper describes a 4-cylinder hydraulic circuit system controlled by a new cross-coupled fuzzy PID, and its leveling algorithm is designed to meet the demand of the loading system for test bed. In order to enable synchronous loading and implement precise leveling control, the output displacement derived from a theoretical model, called Żn, is tracked in real-time. Using AMEsim software, the re...
