本手册中使用以下术语。图1位于
此列表的末尾显示了一个典型的控制回路
使用此列表中的术语标识的组件。
模拟：连续可变（例如，控制水的水龙头
从关闭到全流量）。
自动控制系统：对变化作出反应的系统
或通过调整控制的变量不平衡
将系统恢复到所需状态的其他变量
均衡
算法：生成控件的计算方法
通过操作错误信号或时间序列输出
错误信号的数量。
补偿控制：自动调整的过程
要补偿的给定控制器的设定值
第二个测量变量的变化（例如，室外
空气温度）。例如，热甲板设定值
通常向上重置为室外空气
温度降低。也称为“重置控制”。
控制代理：操纵变量所在的介质
存在。在蒸汽加热系统中，控制剂为
蒸汽和操纵变量是
蒸汽。
控制点：受控变量的实际值
（设定值加或减偏移）。

The following terms are used in this manual. Figure 1 at the end of this list illustrates a typical control loop with the components identified using terms from this list. Analog: Continuously variable (e.g., a faucet controlling water from off to full flow). Automatic control system: A system that reacts to a change or imbalance in the variable it controls by adjusting other variables to restore the system to the desired balance. Algorithm: A calculation method that produces a control output by operating on an error signal or a time series of error signals. Compensation control: A process of automatically adjusting the setpoint of a given controller to compensate for changes in a second measured variable (e.g., outdoor air temperature). For example, the hot deck setpoint is normally reset upward as the outdoor air temperature decreases. Also called “reset control”. Control agent: The medium in which the manipulated variable exists. In a steam heating system, the control agent is the steam and the manipulated variable is the flow of the steam. Control point: The actual value of the controlled variable (setpoint plus or minus offset).
