Control Layer

This paper presents a real-time control architecture for SBR systems with no holding tank. The control approach has been divided into three separated layers in order to accommodate different full-scale scenarios. The lower control layer processes the ORP and DO trajectories to detect the depletion of the denitrification and nitrification reactions in order to automatically interrupt the reaction phases. The intermediate layer has been designed to maintain the total solid mass constant in reactors. Finally, an ammonia controller has been implemented in the supervisory layer that optimises the aeration costs to fulfil the effluent ammonia requirements. The overall control system has been verified experimentally in a 150L pilot plant. In this study, the lower control layer reduced the length of mixing and aeration by approximately 20%. In addition, the experimental validation of the ammonia controller led to reductions of about 30% in the overall aerated fraction.

Abstract:The monitoring and treatment of patients in a care unit is a complex task in which even the most experienced clinicians can make errors. A hemato-oncology department in which patients undergo chemotherapy asked for a computerized system able to provide intelligent and continuous support in this task. One issue in building such a system is the definition of a control architecture able to manage, in real time, a treatment plan containing prescriptions and protocols in which temporal constraints are expressed in various ways, that is, which supervises the treatment, including controlling the timely execution of prescriptions and suggesting modifications to the plan according to the patient’s evolving condition. The system to solve these issues, called SEPIA, has to manage the dynamic, processes involved in patient care. Its role is to generate, in real time, commands for the patient’s care (execution of tests, administration of drugs) from a plan, and to monitor the patient’s state so that it may propose actions updating the plan. The necessity of an explicit time representation is shown. We propose using a linear time structure towards the past, with precise and absolute dates, open towards the future, and with imprecise and relative dates. Temporal relative scales are introduced to facilitate knowledge representation and access.
