2-DOF Fuzzy Schemes for Combustion Turbogenerator Wide-Range Speed Control

This paper presents two feasible realizations of 2-DOF wide-range speed control schemes for combustion turbogenerators. These schemes allow independent tuning of the reference tracking and disturbance rejection characteristics of the control system. The fuzzy approach extends these characteristics throughout the operating space of the combustion turbogenerator. Both realizations can be inserted into the speed control loop of existing control systems without degrading performance until the control system is fine tuned. The controllers can be progressively tuned on-site based on the inspection of current responses. The proposed 2-DOF fuzzy control schemes are suitable for application on actual power plants.
