BİR UÇAĞIN İRTİFA KONTROLÜNDE KLASİK VE BULANIK PD DENETLEYİCİ PERFORMANSLARININ KARŞILAŞTIRILMASI

Abstract

Maintaining desired filght conditions in flight envelope for a long period is the primary control problem in aircraft flight control. Due to internal and external disturbances, dynamic behaviour of aircraft may change in a short period of time. Thus a control system designed for a flight condition, may not provide the desired stability and performance characteristics in case of deviation from the equilibrium point. There are numerous studies regarding flight control in the literature. Most of the applications about the design of fuzzy flight control are in simulation level. In this study, the design of classical and fuzzy PD controller for the altitude control system is analyzed and the results are compared for a very large ,four-engine passenger jet aircraft.
