New approach to PID-control otimization for power station loops

This paper presents a new approach for PID-controller optimization oriented on power station processes. This optimization is fulfilled in the frame of the robust theory approach by using four object-oriented criteria for power station processes. High accurate identification of process and its uncertainties provide the robustness basis of the controller optimization. Procedures of identification and optimization are illustrated by three industrial application examples. The tuning of PI/PID - controllers implemented on the IEC (Israel Electric Corporation) Power Stations provides sufficiently good settings of these controller parameters.
