in this paper, optimization and control of a tubular reactor for thermal bulk post-polymerization of styrene have been investigated. by using the reactor mathematical model, static and dynamic simulations are carried out. based on an objective function including polymer conversion and polydispersity, reactor optimal temperature profile has been obtained. in the absence of model mismatch, desire...

In practice, dynamic positioning (DP) vessels are subjected to complex disturbances as well the magnitude and changing rate constraints of thrusts moments. This study applied a surface controller based on an uncertainty disturbance estimator (UDE) DP vessel with input constraints. The UDE was designed estimate handle disturbances. An auxiliary system (ADS) smooth switching function were employe...
