Abstract:
This paper presents temperature control of a
reactor with high thermal inertia. The reactor chamber
temperature is required to be critically controlled at 300°C. A
non-linear thermodynamic model was developed, and process
parameters were estimated to comply with experimental data by
numerical optimization. A new feedback control structure is
introduced and compared with conventional control systems by
a simulation study. In practice, single sensor control system is
the only possible option for this reactor. Optimal control
trajectory of heater temperature was estimated. The heater
control error with the optimal control trajectory and the control
error of the reactor chamber are incorporated for the PI
controller. The proposed controller performed well, and it gives
minimum ISE (Integral Squares Error) value and also
minimum overshoots compared to others.
