摘要
气动技术具有一系列如可压缩性、可缓冲性、远距离输送能耗低、流量大、流速高、执行元件响应速度快等显著优点,在工业生产中得到广泛应用,它是自动化不可缺少的手段。基于气缸热力学建立了系统的动态数学模型,推导出其传递函数,对气动比例伺服能进行高精度控制提供了理论基础,为改善系统性能提供了指针。通过Matlab仿真,证明所得的传递函数准确可靠。
Pneumatic technology is applied widely in industry for it has a series of obvious advantages, for example, it is compressible and cushiony, could be transported to a long distance with low consumption at high speed and mass flow, and its power elements respond rapidly. Thus it becomes an important part of automation. Based on assay of cylinder thermodynamics the author builds dynamic mathematical model and deduce the transfer function. It provides theoretical base for high accuracy orientation control of servosystem and pointers for improving system performance. The simulation by Matlab software shows that the transfer function is accurate and reliable.
