Feedback Control of Reactor with Axial Dispersion
Original language description
The chemical reactor with axial dispersion and the 1st order kinetic was a subject of analysis and control. We supposed a linear model with distributed parameters and two boundary conditions. The model has single concentration input and output. There areonly two parameters: Peclet criterion and dimensionless kinetic constant. The transfer function of chemical reactor is transcendent with infinite number of poles. It is useful to compare various linear controllers in the feedback from the pedagogical point of view. P, I, PI and PID controllers were set using the Nyquist plot and maximum module technique in frequency domain. The transfer functions of reactor, open and closed loops were studied. The Nyquist plot was used for the estimation of the critical gain of controllers. Then Ziegler-Nichols technique of halving the critical gain was compared with gain estimation using optimum module approach. The Bode plots of FW describe differences among the controllers and the tuning approaches.
