ERROR EVALUATION OF HARDWARE-IN-THE-LOOP SIMULATION OF A GAS TURBINE ENGINE FUEL CONTROLLER

Correct implementation of a fuel control algorithm for a gas turbine engine (GTE) in an electronic control unit (ECU) is one of the basic challenges in the development of a GTE fuel control system. A common measure in such implementation is the error of the hardware-in-the-loop (HIL) simulation test. In this paper, evaluation and diminution of the hardware-in-the-loop test error for a gas turbine engine fuel controller is presented. For this purpose, a fuel controller has been designed for a power generating gas turbine engine. The designed controller was then implemented in the PC104 hardware and tested in an HIL simulation. The test results were then evaluated in order to study the controller functionality. In this study, a procedure is proposed for evaluating the implementation of the fuel control algorithm in PC104 and diminishing the HIL simulation errors. Finally, it is shown that the proposed approach to decreasing the HIL simulation error is effective.
