为满足挤压生产的要求,全苏冶金机器制造科学研究所研制出了一种新的调节器。这种调节器,把速度失调量定为两个频率的频差(这两个频率,分别是给定挤压速度与实际挤压速度。),然后对失调信号进行积分,并把积分结果转换成节流阀阀杆的位置值。积分由可逆计数器完成。当计数器的输入端出现工作脉冲频率瞬时突变时,调节器将大大改变调节回路的调节作用,甚至排除了干扰的影响。该调节器的简化方框图见图1。它包括行
In order to meet the requirements of extrusion production, all metallurgy Machinery Manufacturing Institute of Science developed a new regulator. This regulator sets the speed offset as the frequency difference between the two frequencies, which are the given extrusion speed and the actual extrusion speed, respectively, then integrates the offset signal and converts the integration result Into a throttle valve stem position value. Integral by the reversible counter to complete. When a sudden change occurs in the frequency of the operating pulse at the input of the counter, the regulator will greatly change the regulation of the regulating circuit and even eliminate the effects of interference. A simplified block diagram of the regulator is shown in Figure 1. It includes the line
