中文摘要: |
针对试验台加载系统需具有高效率、快响应和高同步精度的特点,设计了一套液压油路系统,并开发了一种模糊PID交叉耦合同步调平四缸的控制算法。通过对理论模型输出位移的实时跟踪,实现了试验台的同步加载和精确调平控制。基于AMESim建立的同步加载系统的仿真结果,验证了主从式控制与模糊PID交叉耦合控制方案设计的合理性和可靠性。调平系统实验进一步表明,改变四液压油缸负载值使液压油缸负载不同步,可明显提高系统的高精度同步性能。 |

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. |
