An important issue in analyzing a Wastewater Treatment Plant (WWTP) is modelling the disturbances acting on the control loops of the plant, especially in case of urban WWTPs. Although in the literature periodic variations are systematically adopted for the influent description, the control solutions to reject these disturbances are not taken into consideration. This paper aims to establish a WWTP...
In this paper a hierarchical control structure appropriated to recirculating aquaculture processes is proposed. The control software consists in two levels. The first level is the low level and deals with the basic control functions of the process such as: the control of the dissolved oxygen concentration and the temperature monitoring in the aquaculture tanks, the pH control after the mechanical...
