Hi,

see:

https://de.mathworks.com/help/control/examples/control-of-processes-with-long-dead-time-the-smith-predictor.html

and:

https://en.wikipedia.org/wiki/Smith_predictor

Or - if you dont want to read so much: For controllers dealing with dead time behavior there are benefits.

Best regards

Can they deal with network time delay like sensor to controller delay or controller to actuator delay over network ?

[Stephan]

Hard to say, I suggest you implement it and compare the result to your existing model.
