Parameter t is applied as one of the important parameters of AI artificial
intelligence control algorithm. "t" is defined as follows: time needed for a electric
furnace from the beginning of elevating temperature to get to 63.5% against the final
speed of temperature elevating, provided there is no heat loss. The unit of parameter
“t” is second.
For industrial control, hysteresis effect of the controlled process is an important
factor impairing control effect. The longer is system lag time, the more difficult to get
ideal control effect. Lag time parameter “t” is a new introduced important parameter for
AI artificial intelligence algorithm. AI series instrument can use parameter “t” to do
fuzzy calculation, and therefore overshoot and hunting do not easily occurs and the
control have the best responsibility at the time.
The optimal t equals to derivative time in PID control. Parameter “t” gives effect on
proportional, integral and derivative function. If t≤CtI, derivative function of system
will be eliminated.
