摘要
针对碳纤维成型液压机三缸不同步造成的碳纤维增强复合材料压缩性能、弯曲强度、疲劳强度等性能减低的问题,设计碳纤维成型液压机三缸同步控制系统,建立相应的数学模型;运用AMESim/Simulink进行联合仿真,分析三缸同步控制系统的动态特性。仿真结果表明:与PID控制相比,采用模糊PID自适应控制的阶跃响应时间缩短7.36%,在指数负载力和随机负载力工况下,3个液压缸的最大同步误差分别降低44.6%、37.1%、10.7%,16.7%、31.3%、3.5%。
This study is aimed at the reduction in compressive properties,bending strength,fatigue strength,and other properties of carbon fiber reinforced composite materials caused by the non-synchronization of three cylinders in a carbon fiber molding hydraulic press.A three-cylinder synchronous control system for the hydraulic press is designed,according to which a corresponding mathematical model is established,co-simulation experiments are conducted using AMESim/Simulink,and analysis on its dynamics is made.The simulation results demonstrate that compared to traditional PID control,fuzzy adaptive PID control reduces the step response time by 7.36%,and decreases the maximum synchronization errors between hydraulic cylinders under exponential and random load conditions separately by 44.6%,37.1%,10.7%,16.7%,31.3%,and 3.5%.
