MONITORING AND CONTROLLING OF TEMPERATURE IN A GAS PLANT VIA CASCADE ARCHITECTURE

This report discusses the development and implementation of computer eoutrol
on an industrial process plant. The objectives of the project is to design and tune two
different PID controller for the control of temperature in a gaseous pilot plant. The
gaseous pilot plant, located at Universiti Teknologi PETRONAS, is used in the case
study. The focus of the project is on the control and monitoring of the temperature of
gas in the pilot plant.
The PID controller will be designed and simulated via MATLAB/Simulink. The
work involves two main stages, modeling and simulation, and real-time
implementation. Once the PID controller has been designed and simulated via
MA TLAB/Simulink, the model will be interfaced to the plant via an xPC target card for
real-time analysis.
The result of this investigation shows that the cascade control architecture
would be a viable method to be used in plant process control. The cascade configuration
that indicates the better performance can specifically be defines to use the Ziegler
Nichols closed loop tuning method for the primary loop, while for the secondary loop
the Cohen Coon tuning method is preferable.
