Abstract:
A comparison between performances of fuzzy PID self tuning temperature
controller and a conventional on-off temperature controller for cold store was
done. A fuzzy PID self tuning temperature controller was designed to replace
the conventional on-off temperature controller to maintain the inner
temperature of a cold store kept at the desired value. Both temperature
controllers of the conventional system and the fuzzy PID self tuning were
designed and evaluated using MATLAB/SIMULINK software. The
simulation shows that the fuzzy PID self tuning controller was found to be
more consistent and effective in maintaining the inner temperature of the cold
store, at the desired value than the conventional on-off controller. Both
simulation results provide full graphical development which is analyzed and
have been compared. The effectiveness of the fuzzy PID self tuning control
system and its ability to maintain the inner temperature of the cold store
consistently than the conventional on-off controller is shown.
