Fault tolerant flight control system design to a rotary wing aircraft

Abstract

In this study, fault tolerant control is made using improved PID controller approach with different motor fault scenarios in a quadrotor. A realistic simulation was set up by obtaining dynamics equations of aircraft and modeling motor dynamics. By linearizing nonlinear model suitable controller is formed and this controller scheme is used in nonlinear models. Finally, designed control structure over different motor fault scenarios is tested whether a robust control structure is built. When the simulation results are analyzed, the performance of the designed control system shows a robust behavior under various conditions.
