what is the difference between auto tuning and manual tuning of controllers(eg:PID,PI,PD CONTROLLER..

Answer / s.sasikumar

the above is correct. in auto tuning the parameters of
P,I,D values varies automatically with respect to feedback
values and it takes several hours to be in stable at
setpoint where in manual the operator has to give the P,I,D
values manually by taking the response in graph as per
zeigler-nichols method . And it consumes half of the time
to be in stable at the set point when compared to auto
tuning.

Answer / mahesh kumar

In Autotuning the loop (PID, PIED etc.)are tuned with help
of the S/W, only by pressing the autotune button the S/W
autometically tune the gains while manual tuning the
programmer set all the gains manually. Manual Tuning is
just like hit & Trial Process.
