Abstract

In this paper, the design scheme of fractional order proportional integral (FOPI) controller for the second order plus time delay model of aeration of activated sludge wastewater treatment process are presented. It is found that the two controllers designed by the proposed tuning method not only make the system stable, but also improve the performance for the aeration control of activated sludge wastewater treatment processes. Simulation results are presented to validate the proposed tuning schemes. Furthermore, from the simulation results, it can be seen that the fractional order PI controller outperforms the integer order PID controller.
