Integral control

In the integral control,the change of the value of the controlled variable has a preset relationship with the time from the control system output control to the actual effective time.The output of the actuator gradually reaches the set value.The generation of this control method is due to the fact that it often takes a period of time for the actual control elements and actuators to give the output signal to make the controlled variable reach the set value.

积分控制

在积分控制中，被控变量的值的变化与控制系统输出控制到实际生效的时间有一个预先设定的关系。执行机构的输出是渐渐地达到设定的值的。这种控制方式的产生是由于实际的控制元件和执行机构从给出输出信号到使被控变量达到设定值往往需要一段时间。
