采样调节是近代应用新的自动化技术工具进行自动调节的一种新调节方式,它主要是使调节器输出在一段时间内按调节器规律计算出来的输出值“放行”出去,而在另一段时间内保持输出值不变。这两段时间可以相等,也可以不相等;前者叫作“开门时间T_K,后者叫作闭门时间T_B”。这两段时间之和,叫作“采样周期”,也是可长可短的。通常直接数字控制(DDC)的采样周期很短;而且开门时间T_K比闭门时间T_B更
Sampling and adjusting is a new adjustment method of automatic adjustment in modern application of new automation technology tools. It mainly “releases” the output value of the regulator output calculated by the regulator for a period of time, and at another time Keep the output value unchanged. These two periods of time may or may not be equal; the former is called “open door time T_K, the latter is called closed door time T_B”. The sum of these two periods, called the “sampling period,” can also be long or short. Usually the direct digital control (DDC) sampling period is very short; and the door opening time T_K is more than the door closing time T_B
