Closed Loop Identification of Distillation Column

Approaching to the current era of modernization, growing technology is vital
especially in oil and gas industry. Nowadays in industries, loads of storages in the
form of columns are kept but the most regular and common column used is
distillation column. It is widely used everywhere. To be precise, determination of the
output is called the feedback signal and the type of system uses is known as closed
loop system. Closed loop system identification is a process of enhancing or
developing the mathematical representation of a physical system with a feedback
control whereas open loop system identification is the mathematical representation
without a feedback control.
