摘要

研究连续系统的传感器故障估计问题

提出一种奇异观测器来进行故障估计

所提方法不需要假设故障、故障导数和干扰的上界已知。通过HB∞性能指标抑制了干扰对故障估计的影响;采用线性矩阵不等式来获得奇异观测器的增益阵;利用Lyapunov泛函得到了观测误差动态系统的鲁棒渐近稳定性;最后通过飞行器仿真实例验证了所提方法的有效性。

Abstract

The sensor fault estimation problem for continuous system are studied

a descriptor observer is proposed to employ fault estimation

and the proposed method doesn’t need assuming that faults or faults derivative and upper bound of disturbance should be known. The influence to fault estimation caused by disturbance is suppressed by the HB∞performance index; linear matrix inequality is utilized to obtain the gain matrices of the descriptor observer; the robust asymptotically stability of the observer error dynamic system is derived by Lyapunov function;finally

an aircraft simulation example is exploited to illustrate the effectiveness of the proposed method.
