Reconfiguration of a Thermofluid Process using a Virtual Actuator

Keywords: fault-tolerant control, control reconfiguration, virtual actuator, process control

The application of the virtual actuator to the reconfiguration of a thermofluid process after actuator faults is described. The virtual actuator is a model-based, autonomous and online approach to reconfiguration of faulty processes after successful diagnosis. Several design approaches known from the literature are applied and tested experimentally for three actuator failure scenarios on the thermofluid process. The faults break the loop prior to reconfiguration. The process is described and a model is given as a basis for designing the virtual actuator. The experimental results are analysed and discussed thoroughly, also with respect to future research.
