| Summary: | Abstract
A boiler drum and heat exchanger QAD Model
BDT921 that is installed in the Control Laboratory
is being used as a model plant to achieve the digital
control system design since it is analog in nature.
The digital control design need a mathematical
model of the system is designed. This paper covers
a discrete time model of boiler drum and heat
exchanger QAD Model BDT 921. The model is
obtained from parameter gain values of the real
system and then this model will simulate using
MATLAB program. The proportional integral
differential (PID) controllers are being chosen as
the control element in discrete form as the real
system is using the same control element. The
output responses behave as the second order
system with a closed correlation in rise times and
peak times compared with data obtained from
experiment and simulation results. With regarding
to the analysis done, the digital control can be
implemented to the boiler drum and heat exchanger
control system and for further viewing, to be
controlled digitally with computer in the control
room. |
