SYSTEM IDENTIFICATION APPLIED ON VARIOUS FORMS OF CONTROL TANK SYSTEM

Control Tanks are widely used and are considered as general equipment in
the industry today. Therefore, it is required to have a good control system or control
analysis specifically for the system. For any control analysis, it is desirable to be
able to obtain a model of the tank system to allow complete off-line analysis with
minimum interference to the process. This paper concerns the system identification
of various form of control tank system used in the industry today. It simplifies the
approach to identification and presents the use of analysis in a more readable,
understandable and general manner. Through mathematical modelling, MATLAB
simulation and technical computing the whole system can be characterized based on
the relevant parameters for a variety of tank formations. This method presents the
user to identify and know the system characteristic of the control tank system
through simulation study and hence, help to design the best possible operating
method to be used in real industry application. Through this simulation study, each
type of system can be characterized individually and independently based on the
flow rate and the height of the tank. Initially through mathematical derivation, the
modelling is then performed and simulated using the Simulink application in
MATLAB. An important stage in system identification process is the selection of
the type and characteristics of each type of the tank system and this is the subject of
this paper.
