Design of a supervised control system for a sludge dewatering process

The effect of changes in operating conditions due to fault occurrences can alter performances in industrial processes. One way of preventing performances from degradation is to develop a supervised control system, which has the capabilities of maintaining the functioning of the process under acceptable operating conditions. In this paper, an accommodation procedure for the supervised control system is presented. The closed-loop system is modelised by means of a clustering approach. An accommodation module generates new set points or control parameter values for the degraded process. This approach has been successfully applied to a centrifugation process.
