| Abstract: |
| Aiming at high efficiency,fast response and high synchronization precision for the loading system a test rig,a set of hydraulic circuit system was designed and a fuzzy PID cross-coupling leveling control algorithm of synchronously driving fourcylinders was created.In order to synchronously load and implement precise leveling control of the test rig,the output displacement of a theoretical model was tracked in real-time.The simulation results of AMESim model of the synchronous loading system verify that the combined design scheme of master-slave control and fuzzy PID cross coupling control are suitable and reliable.And the leveling system experiment further shows that adjusting the load value of the fourcylinders to meet the demand of its un-synchronization can improve significantly high precision synchronization performance of the leveling system. |
