Abstract: A dynamic multi-objective particle swarm optimization based optimal control method is provided to realize the control of dissolved oxygen (SO) and the nitrate nitrogen (SNO) in wastewater treatment process. In this method, dynamic multi-objective particle swarm optimization was used to optimize the operation objectives of WWTP, and the optimal solutions of SO and SNO can be calculated. Then PID controller was introduced to trace the dynamic optimal solutions of SO and SNO. The results demonstrated that the proposed optimal control strategy can address the dynamic optimal control problem, and guarantee the efficient and stable operation. In addition, this proposed optimal control method in this present invention can guarantee the effluent qualities and reduce the energy consumption.
