摘要
针对双系统中执行元件存在负载不均衡、泄漏量不同、摩擦力不等和制造误差等因素,会产生执行元件在工作过程中不同步的现象,该文进行控制系统设计,建立阀控液压缸系统数学模型,设计梁底悬挂运梁机双液压系统,运用AMESim-Simulink软件对双液压系统进行同步控制仿真分析。仿真结果引入常规PID与模糊PID进行对比分析,显示梁底悬挂运梁机双系统在模糊PID控制下同步控制精度提高65%,证明了应用模糊理论的梁底悬挂运梁机双系统同步控制策略的有效性。
In view of the factors such as unbalanced load,different leakage,unequal friction and manufacturing error of the actuator in the dual system,the actuator will not be synchronized in the working process.In this paper,the control system is designed,the mathematical model of valve controlled hydraulic cylinder system is established,the double hydraulic system of beam bottom suspension beam conveyor is designed,and the synchronous control simulation analysis of the double hydraulic system is carried out by using AMESim Simulink software.The simulation results are compared and analyzed by introducing conventional PID and fuzzy PID.It shows that the synchronous control accuracy of the double system of beam bottom suspension beam conveyor under Fuzzy PID control is improved by 65%,which proves the effectiveness of the synchronous control strategy of the double system of beam bottom suspension beam conveyor based on Fuzzy theory.
