The Impact of Sensor Errors on Flight Stability

Sensors play a significant role in flight control systems. The accuracy of the measurements state variables affects quality and effectiveness stabilization. When designing closed-loop systems, it is desirable to use sensors highest class reliability, signals which will be as error-free possible. False indications lead malfunctioning stabilization system, its operation does not meet requirements set for it. There are many types errors—bias, white noise, hysteresis, or bias drift—which affect measurement from sensors. One problems assessing what maximum level sensor errors system still operate required. In this paper, impact different on was presented. research carried out using example an automatic aircraft trimming surfaces longitudinal channel Hardware-in-the-Loop simulations. model simulates various during flight, while implemented hardware interfaced with real-time computer. results simulations presented analyzed.
