基于模型参考自适应的磁流变阻尼器故障容错控制
Fault-tolerant control of magnetorheological damper based on model reference adaptive
摘要
Abstract
In order to better solve the problem of robust fault-tolerant control for magnetorheological landing gear buffer systems with damper failures,a model reference adaptive fault-tolerant control strategy was proposed,and a mechanical model was established and key parameters were determined by damping experiments.A fault model was established for the magnetorheological landing gear system and fault-tolerant control was introduced.An adaptive law was designed to adjust the control gain in real time,and a fault-tolerant controller was constructed to deal with damper failures.Results show that compared with the traditional passive and model reference adaptive control methods,the buffer efficiency of the damper fault tolerant control method is improved by 4.9%and 0.95%respectively.This control method significantly improves the damping efficiency and quality of the magnetorheological landing gear damping system.关键词
