Model-based control of slugging: advances and challenges

Model-based control of slugging: advances and challenges

We review recent advances in the suppression of the slugging phenomenon by model-based control. We focus on three aspects of recent contributions: models, observers and control laws. For each category, we evaluate and compare existing solutions, and propose directions for improvement.

Boundary control for stabilization of slugging oscillations

The problem of suppressing the slugging phenomenon is investigated. Industrial oil facilities such as gas-lifted wells and offshore production oil-risers are examples of systems where occurs such phenomenon. To study this problem, we consider that these systems are written as a set of 3 × 3 hyperbolic partial differential equations of balance laws, where the control variable appears at the boun...

Advances and Challenges in Control Education

Control Engineering is the engineering field that deals with the modeling of dynamic systems and the design of controller or regulatory set-ups that will cause those systems to behave according to some desired specifications. The advancements in technology, the development of sensors, activators and suitable IT tools are the main factors that made autonomous systems possible. In view of these d...

Monoclonal Antibodies as Therapeutic Agents: Advances and Challenges

Despite the major advances in conventional forms of treatment (i.e. surgical techniques, radiotherapy and chemotherapy) and improved survival rates, cancer is still the second leading cause of death in developing countries. One major limitation of cytotoxic drugs and radiation in the treatment of cancer patients is their inability to discriminate between malignant and normal tissues. This in tu...
