摘要
文章的主要研究对象是液压支架试验台调高控制系统。通过对升降液压系统的分析,找出影响同步性能的因素,进而对系统的同步性能进行研究。多级液压缸同步起竖系统受力复杂,利用AMESim软件构建了二级液压缸4缸同步控制系统模型,并对其液压系统的性能进行分析。采用AMESim与simulink联合仿真的方法,对PID控制、模糊控制在多级液压缸同步控制中的应用进行了研究,经分析最后使用模糊-PID控制算法的方法。仿真结果表明,该控制算法能较好地满足升降系统对同步精度与稳定性的要求。
The main object of study of the article is to increase the hydraulic support test bench control system.Lifting hydraulic system analysis to identify factors that affect the synchronization performance,and thus the synchronization performance of the system.Multi-stage hydraulic cylinder synchronous erection system are complex,using AMESim software to build two hydraulic cylinder four-cylinder synchronous control system model and analyze the performance of its hydraulic system.AMESim and simulink simulation method,the PID control,fuzzy control has been studied in multi-stage hydraulic cylinder synchronous control,the last to use the method of fuzzy-PID control algorithm analysis.The simulation results show that the control algorithm can meet the requirements of the lift system synchronization accuracy and stability.
