Study on Variable Universe Fuzzy PID Control for Landing Gear Based on MRF (Magneto-rheological Fluid) Damper

摘要

Aircraft landing gear shock system model was established,the system vibration differential equation and state-space equation were deserved.Based on the general fuzzy PID controller,the idea of fuzzy PID controller and its application in shock absorber system were studied.Based on MATLAB,the system simulation model was established,and the fuzzy PID control of semi-active suspension is analyzed compared to variable universe fuzzy PID control.The results show that the variable universe fuzzy PID control had better control effect.
