【摘要】 针对高速数控压机液压系统的开发,对比例控制系统进行理论分析与研究,通过对液压系统的建模,建立起比例阀控非对称液压缸的数学模型,根据所研究的实际情况对模型进行必要的分析和修整。并运用仿真软件Matlab分析系统建模级确定PID控制参数,主要对PID控制器进行设计。通过PID控制器使得高速数控压机系统满足工作要求。更多还原

【Abstract】 Refer to the development of the high speed numerical control oil-press system,this paper makes a theoretical analysis and study about proportional control system.Through setting up the mathematical model of proportional valve controlled non-symmetry hydraulic cylinder via the hydraulic system model building.Then analyzes and modifies the model based on the matter of this study,and simulates the model with Matlab software to confirm PID parameters,thus designs the PID controller.The high speed numerical control oil-press system satisfies the requirement of normal work.更多还原
