Abstract
Continuous Stirred Tank Reactor (CSTR) is a major area in process,
chemical and control engineering. In
this paper, PID and MPC controllers are designed for CSTR in order
to analyze the output concentration of the
system by comparing the two proposed systems using Matlab/Simulink.
Comparison have been made using two
desired concentration input (Random reference and step) signals with
and without input side disturbance (Flow rate
error). The simulation result shows that the continuous stirred tank
reactor with MPC controller have better response
in minimizing the overshoot and tracking the desired concentration
for the system without input disturbance and
with the effect of the disturbance makes the continuous stirred tank
reactor with MPC controller output with small
fluctuations and still better than the continuous stirred tank reactor
with PID controller. Finally the comparative
analysis and simulation results prove the effectiveness of the continuous
stirred tank reactor with MPC controller.
