| 摘要: |
| 研究了基于终端滑模观测器的飞机防滑刹车系统执行结构故障重构的方法。针对常规滑模观测器渐进收敛而影响执行机构故障重构的时效性问题,利用终端滑模控制所具备的有限时间收敛特性,并且考虑实际系统故障信息未知的情况,构造非奇异终端滑模观测器(NTSMO)保证所有状态在有限时间内收敛于零,在等值控制方法的基础上给出了执行机构故障重构律。最后通过MATLAB仿真验证了所提方法的有效性。 |

| Abstract: |
| A method of fault reconstruction, which is based on terminal sliding mode observer, is proposed for aircraft anti-skid braking system. In the traditional sliding mode observer, the estimated error of unmeasured state is asymptotic convergence, which affects the timeliness of actuator fault reconstruction. In response to the above problem, the property of finite time convergence of terminal sliding mode is used to build a nonsingular terminal sliding mode observer (NTSMO), which ensures that all of the state estimation errors converge to zero in a finite time with the unknown actuator fault. Accordingly, a reconstruction law based on the specific equivalent control approach is then designed to accurately estimate the value of actuator fault in real-time and online. The performance of the proposed scheme is evaluated extensively through numerical simulations with MATLAB. |
