ANALYSIS OF THE MAJOR APPROACHES TO THE DESIGN OF MULTIVARIABLE DECENTRALIZED CONTROL SYSTEMS FOR DISTILLATION COLUMNS
MetadataShow full item record
Decentralized control structure is the most common for control systems of distillation columns. It has the following advantages: easy digital realization, free structure that allows to change controller tunings in any time, easy diagnostic of non-working loop. The aim of this work is to analyze major approaches of decentralized control systems design, find their advantages and disadvantages in application to distillation process control problem.
