An applied research of linear interpolation fuzzy PID control method in aircraft landing gear shock absorber system

According to the basic structure of the aircraft landing gear, through the mechanical analysis, we established the mathematical model of the aircraft landing gear of semi-active damping system, and a linear interpolation method was applied in the fuzzy controller queries to adjust the PID parameters automatically. We have used the Matlab / Simulink control system simulation software for aircraft landing gear model computer simulation, and compared with conventional fuzzy PID landing gear shock absorber system. The results show that the aircraft landing gear with the linear interpolation fuzzy PID controller is better than conventional fuzzy PID landing gear shock absorber system in the slow landing, taxiing of the aircraft.
