In this paper, the application of a Symmetric-Send-on-Delta event-based proportional-integral controller to a microalgal raceway photobioreactor is presented.

Abstract

In this paper, the application of a Symmetric-Send-on-Delta event-based proportional-integral controller to a microalgal raceway photobioreactor is presented. It is shown that the event-based mechanism can be simply added to a classical time-driven PI controller, what allows simplifying the overall design of the event-based approach. The influence of the Delta threshold value is evaluated, and the results of the event-based architecture are presented in simulation and compared with a standard time-based PI controller. It is demonstrated that the event-based controller achieves the required performance by reducing the use of the actuator and saving costs related to gas consumption.
