In Silico Comparison for Smith Pbkp_redictors Applied to Processes with Elevated Delay and Noise Effects

Abstract:

This work presents an analysis and comparison of the Filtered Pbkp_redictive Proportional and Integral controller and the control schemes of two degrees of freedom of Zhang et al. and Mejía et al. when the sensor signal has noise and when it has no noise. These control schemes are tuned by different optimization algorithms and tested in a chemical process that presents a dominant time delay. Controller performance is measured using integral square error, total variations of control efforts, maximum overshoot, and settling time. The results show that control schemes compensate for the dominant time delays but are affected when the sensor signal has noise.
