Active methods of increasing reliability of FBW control systems for small aircraft

Abstract

The main task presented in this paper is connected with increasing the reliability of fly‐by‐wire control systems. The control systems feature a high degree of automatization and employ an intuitive, human‐centered way of piloting, makings the aircraft pilot‐friendly. But the most important feature of these control systems is safety. Increasing reliability is strongly connected with growth in safety. The high degree of automatization enables the use of different kinds of reconfiguration as an active method of increasing reliability. In this paper, special attention is paid to methods of fault detection and isolation, especially in sensors and actuators connected to the fly‐by‐wire system. These methods are necessary to build a fault tolerant control system.
