Hello friends
I'm trying to use Fb58 in place of FB41 in furnace application.
I've supplied all basic parameters to FB58. I'm using a specially developed simulation program for testing of FB58.
Problem is that when ever i try to auto tune the controller
for fix rate of temp. increase,controller output %, Deviation in output for excitation & step change in setpoint the PID values every time i get are totally diffrent.
In short there is no repeation for PID parameter for fixed process conditions..
can any 1 kindly tell me a reason for this..is there any problem in parameters
Plz reply
thanx
