Hi,
Am desiging an adaptive MPC contoller for a non linear plant using online model estimation, the objective is to control the rolling speed of hot rolling steel mill. I have done all the design procedures and connected all related blocks, simualtion was successful but when it comes to the result am having an oscillatory overshooting before the output starts to track the reference signal. Any advice on the reasons?

Hi
If system does not have complex poles, then there is no chance for oscillatory overshoots. So, make sure that your system design does not lead to complex poles.
This link might be helpful for you to understand in limiting the overshoot :

Thanks Siriniharika for the answer.
Yes my system has complex poles. But the system design is specified physically in a set of differential equations and parameters with values which make the state space model of a certain nature, i can't modify.
I still need your support please.
Thanks in advance.
Ibrahim
