Design of a fuzzy controller, to achieve a precise control of the hydraulic cylinder position by the high-speed on-off valve was based on PWM.
设计了一种模糊控制器,实现了PWM高速开关阀控液压缸位置系统的精确控制。
IC card can also record the running situation of water meter, and manage total using amounts, total purchasing amounts and on-off valve state under control of managing computer or managing software.
IC卡还能记录表的运行情况,在管理机或管理软件下将表的总用水量、总购水量、开关阀状态等信息进行管理。
The average flux of the PWM high-speed on-off valve are regulated by the Pulse-Width Modulation theory and it is easy to combine the computer and hydraulic control technology.
高速开关阀采用脉宽调制(PWM)原理来控制其平均流量,极易实现计算机控制技术和液压技术的有机结合。
