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。结合调平系统实验,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。
英文摘要:
      Aiming at the characteristics of high efficiency, fast response and high synchronization precision for loading system of test rig, a set of hydraulic circuit system was designed and a fuzzy PID cross coupling leveling control algorithm of synchronous driving four-cylinder was created. In order to synchronous loading 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 synchronous loading system verify that the combined design scheme of master-slave control and fuzzy PID cross coupling control are rational and reliable. And the leveling system experiment further shows that adjusting the load value of four-cylinder to meet the demand of its un-synchronization can improve significantly high precision synchronization performance of leveling system.
