IMPLEMENTATION OF PID CONTROLLER IN CASCADE MODE FOR TWO TANK SYSTEM

This report basically discusses the research done and basic understanding
of the chosen topic, which is Implementation of PID Controller in Cascade
Mode For Two Tank System. The objective of the project is to improve the
efficiency of the process control on the Mobile Flowmeter Calibration Trainer
through implementation of PID controller in cascade mode. Whereas in the
existing system, the controller used to control the flow of the plant is working in
single mode which is less efficient. This pilot plant is equipped with three
different flowmeter which are Coriolis Flowmeter, Vortex Flowmeter and Orifice
Flowmeter. The Coriolis Flowmeter is used as the master flowmeter and two
others flowmeter can be connected in series with master flowmeter. In addition
this project will also include the installation of two channel flat bed recorder on
the pilot plant. This project will begin with numerous researches either by joumal
references or seeking internet information that accomplished based on the project
title. In order to seek out for significant information, the next action to be taken is
consulting certain problem regarding to the process control with expert technician.
Several experiments will also be conducted as the introduction to have basic
knowledge towards the plant. The scheduled experiments are Comparative Study
of different Flowmeter and Flow Control and Controller Tuning. Then, fine tuning
method for optimum controller technique and MATLAB simulation will be
conducted. The performance of PID controller in single mode operation and
cascade control will be compared. At the end of this project it is hope that the
efficiency of process control for Mobile Flowmeter Calibration Trainer can be
improved.
