提出了一种具有特定类型的开关控制的液压系统的建模。尽管传统的液压驱动技术希望压力和流量的相当平滑的变化,并且振荡构成不希望的现象,但是开关控制引起振荡作为不可缺少的元件,以通过阀控制实现高能量效率。所研究的系统是一个,其中包括一个新的开关阀,一个相当长的线波传播动力学,液压缸,和阀门的动态。
Modelling of a hydraulic system featuring a specific type of switching control is presented. Despite conventional hydraulic drive technology where rather smooth changes of pressure and flow rate are intended and where oscillations constitute undesired phenomena, switching control provokes oscillations as an indispensable element to achieve high energetic efficiency with valve control. The system under study is one which comprises a novel switching valve, a long line with considerable wave propagation dynamics, a hydraulic cylinder, and the valve's dynamics.
