Performance Analysis of Robust Averaging Level Control
2011 (English)Report (Other academic)
Frequent inlet ﬂow changes, especially in the same direction, typically cause problems for averaging level controllers. To obtain optimal ﬂow ﬁltering while being robust towards future inlet ﬂow upsets closed loop robust MPC was used. Its performance and robustness is analyzed and compared to the optimal averaging level controller. The knowledge gained from the robust MPC exercise is also used to propose a robustiﬁcation of the optimal controller. Both the analysis and the simulation results show that the robust controller obtains comparable ﬂow ﬁltering as the optimal controller even when inlet ﬂow changes are sparse while handling frequent upsets considerably better.
