Ten Years of Full Authority Digital Electronic Engine Control Development at the Budapest University of Technology and Economics, Department of Aeronautics, Naval Architecture and Railway Vehicles

Abstract

Gas turbine power plants are equipped with full  authority digital electronic control (FADEC), thanks to their improved accuracy, reduced mass, and dimensions and maintenance requirements. At BME DANAR and its predecessor, the development of electronic control systems has begun in 2009 after  TKT-1 turbojet engine test bench entered service. This paper introduces the main steps of the work on the initial and other types (PD-60R and Deutz T216), and the different control laws (rotor speed, Engine Pressure Ratio and Turbofan Power Ratio). Furthermore, the authors present those algorithms (PID, linear quadratic and sliding mode control) which have been implemented in their FADEC systems. Probably the most important advantage of the presented work is that it has been validated in real gas turbine environment.
