P = proportional or gain, the one you got from the equation of response graph
I = Integral, for minimizing the offset.
D = Derivative, for high respon and less dead time
rset = set point value
the integral and derivative constant is derived from the ziegler nichols, ciancone, and many...
Thanx for the reply, Mr Samiran.
i want to tune my controller in ZN online methode, and get the best value for PID constant. the procedure is :
1. set the extreme value of integral time(eg :ti = 100,000)
2. set the small value of proportional time (eg : 0.5) if the graph is converges, it means...
Hi :) my name is napz
i have a problem in using HYSYS. i'm dealing with PID controller and i can't get the oscillation graph.
the kc value for oscillation graph is between converges and diverges graph. the problem is when i set the appropriate kc, HYSYS is running for a few minutes seems like...
