《调节器的实际积分时间常数T_I~*=FT_I吗?》一文作者认为在三作用情况下,P=100%的积分时间仍然是测量积分过程中输出变化一个单位(文中设定为2 mA)所需要的时间,我们认这是错误的。积分时间应该是测量积分部分重复一次比例所需要的时间,调节器在三作用情况,对阶跃输入的输出响应函数是:
“Is the actual integration time constant of the regulator T_I ~ * = FT_I?” The author considers that the integration time of P = 100% is still one unit of the output change during measurement integration (set at 2 mA in this paper) The time needed, we think it is wrong. The integration time should be the time required to measure the fraction of repeats of the integral. The regulator’s response to the output of the step input in the three-acting case is:
