A description of an experimental model is presented wich has the purpose of controlling the dissolved oxygen concentration (DOC) in a water tank where marine species are raised. The control model considers an on-off algorithm that's monitored remotely and can be modified by means of a web application. The model includes all perturbations that affect the DOC, such as: temperature, salinity, atmospheric...
The load flow has a stochastic character due to the high penetration of renewable generation, especially wind power. Nowadays about 50 GW of wind power is installed in the UCTE power system. This causes difficulties especially in the optimal operation of the system and can lead to black outs due to problems with energy flow which is often not produced according to demand. An example occurred on November...
The paper proposed to use recurrent fuzzy-neural multi-model (FNMM) identifier for decentralized identification of a distributed parameter anaerobic wastewater treatment digestion bioprocess, carried out in a fixed bed and a recirculation tank. The distributed parameter analytical model of the digestion bioprocess is reduced to a lumped system using the orthogonal collocation method, applied in three...
Accurate mathematical models, to describe and analyze complex systems, cannot be established. This is especially true for biological complex systems because of the complexity of interaction among constituent units inside the whole system. Descriptor biological complex systems are a new research field in descriptor systems; there has been little research about passivity and optimal control of descriptor...
