−−This paper describes a procedure to find the best controlled variables in an economic sense for the activated sludge process in a wastewater treatment plant, despite the large load disturbances. A novel dynamic analysis of the closed loop control of these variables has been performed, considering a nonlinear model predictive controller (NMPC) and a particular distributed NMPC-PI control struc...

The shipping industry plays a vital role in the global economy, with container being one of critical components. Shipping companies outline time for customer stripping days its contracts. availability containers depends on days. days’ tardiness will hinder containers. Therefore, it is fundamental to monitor both actual condition and contract estimate prompt customers expedite unloading process....

The article gives the analysis of optimizing digital controller automatic control system (ACS) a continuous object. procedure for replacing with discrete has been analyzed. original optimized ACS illustrated. It stated that and its elements (all or particular) can be modeled by models described difference equations, not differential ones, as is done in case models. specification sampling period...
