Unloading control system consists of digital controller the signal processing circuit the implementing agency feedback device and other components .

卸 荷控制系统由数字控制器、信号处理 电路、执行机构、反馈装置等部分组成。

Production for boom of gun and its unloading circuit

炮鸣的产生及其 泄 压 回路

Development of the Hydraulic Unloading Circuit and Valve for Laser Leveling Machine

激光平地机液压 卸载 回路及阀的研制

At the same time controller read the position signals of the unloading balancing block through the input signal processing circuit which is used to adjust the output control signals these make up a closed loop control system .

同时控制器通过输入信号处理 电路 读取反馈装置的位置信号，调整输出的控制信号，从而构成了闭环控制系统。
