摘要
以四台空心液压缸支撑大断面箱型梁同步控制系统为研究对象,设计了基于电液比例伺服阀的液压同步系统,建立了系统的数学模型,进行了控制策略分析以及控制器设计,即整体系统采用同等方式的控制策略,每个独立系统采用基于RBF的单神经元PID控制器进行闭环控制。最后,仿真结果验证了该控制方法的有效性。
With four hollow hydraulic cylinder supporting large cross section box beam synchronization control system as the research object, based on electro-hydraulic proportional servo valve of hydraulic synchronization system, established the mathematical model of the system, analyzed the control strategy and controller design, the whole system adopts the control strategy of the same way, each independent system with single neuron PID controller based on RBF closed-loop control. Finally, the simulation results demonstrate the effectiveness of the proposed control method.
