在工艺过程控制中使用电子计算机,可以做到:大大增加被调参数的数量(由一般调节器的2～5个参数增加到数百个,在个别情况下,甚至可以增加到数千个被调参数);实现复杂的控制运算;由一种控制运算很容易地转换到另一种新的控制运算;由于设有记忆装置,可以记录被调对象的运行状态。空调系统属于工艺过程控制的典型被调对象。它的特点是:被调参数的数量大(如多区空调系统);在空调系统的运行中,存在节能的最佳处理空气流程——最佳工况。
The use of an electronic computer in process control can increase the number of parameters to be adjusted (from two to five parameters of a general regulator to several hundred, and in individual cases it can even increase to several thousand. Tuning parameters); to achieve complex control operations; from one control operation can be easily converted to another new control operation; due to the memory device, you can record the status of the transferred object. Air conditioning systems are typically tuned for process control. It is characterized by a large number of parameters to be adjusted (such as a multi-zone air-conditioning system); in the operation of the air-conditioning system, there is an energy-saving optimal process air flow - the best conditions.
