| 英文摘要 | In this paper, a feed forward-cascade controller for dissolved oxygen concentration in an activated sludge process is designed in order to meet stricter effluent quality standards at a minimum cost. conventional proportional and integral (pi) constant dissolved oxygen set-point control and feed forward-cascade dissolved oxygen set-point control are evaluated using the reduced model of activated sludge model no. i and reduced iwa simulation benchmark. the feed forwa rd-ca scade control has been based on a hierarchical structure where a high level or cascade control selects the set-point ofthe low level or conventional controller and low level directly control dissolved oxygen concentration. and feedforward control is introcluced in the control system for preventing the influent loading from influencing the system. simulation results show that feed forward - cascade control of the activated sludge process is more successful than conventional pi control in meeting the effluent standards and reducing operational costs. this control strategy can be expected to be accepted by the operating personnel in wastewater treatment plants.
