It is a one - way flow control valve which can regulate the flow of compressed air in air passage . it will control forward flow , and not control reversed flow , so as to change the one - way movement speed of executive components such as air cylinder
单向型流量控制阀，在气路中调节压缩空气的流量，气源正向流动时节流，反向流动时不发生节流，以改变气缸等执行元件的单向运动速度。
This paper studies an ac servo system with the permanent magnet synchronous motor ( pmsm ) as the executive component . the disadvantages of the conventional methods of ac servo system are demonstrated by computer simulation and by analyzing the mathematical models of the pmsm and the vector decoupling control strategy . then , an improved double - pi combined with variable structure servo controller is proposed
通过对永磁同步电动机的数学模型和矢量解耦控制策略的理论分析，以及基于双pi结合单p位置调节的伺服系统的仿真实验，揭示出经典的伺服控制方法的缺陷，并提出了一种改进的双pi结合变结构的三闭环调节的伺服控制器设计方案。
