FRACTIONAL ORDER-BASED PID CONTROLLER DESIGN WITH GENETIC ALGORITHM (FOPID-GA) FOR AIRCRAFT LANDING GEAR SHOCK ABSORBER MECHANISM

Deterioration conditions of the runway surface (deep track, cracking, raveling, and potholes ) and contaminants greatly affect the landing performance of the aircraft. In this research study, an optimal fractional order proportional integral and derivative controller (FOPID-GA) is designed with a genetic algorithm for the smooth operation of aircraft landing gear systems. To prove the effectiveness, performance, and accuracy of the proposed approach, a comparative study of the new technique and the traditional controllers such as PID, PID-TD, FOPID-TD, and PID-GA controllers was conducted on the MATLAB/Simulink platform. The simulation results clearly show that the proposed FOPID-GA controller outperforms the existing controllers in terms of performance, and damping accuracy. The effectiveness of the FOPID-GA controller is evaluated through simulation studies, demonstrating its potential to enhance aircraft landing gear performance and safety under adverse conditions.
