摘要
The shimmy of nose landing gear is a complex kind of self-excited vibration and it can grave damage to aircraft. The magnetorheological damper (MRD) is used to absorb the vibration energy to inhibit shimmy. In this paper, landing gear and MRD are conceived as a whole, and several specific model-independent control strategies based on error feedback are designed. To improve the performance of active disturbance rejection control (ADRC), phase compensation active disturbance rejection control (PCADRC) is proposed. The simulation results indicate the proposed method has a greater control effect compared with the others. For parameter perturbation and external disturbance, PCADRC also has good robustness and disturbance rejection properties. • MRD is applied to the nose landing gear of the aircraft for shimmy inhibition. • ADRC and fuzzy logic control are designed for the system. • For lag of phase, PCADRC method is proposed and has great effect.
