【摘要】 提出了一种传感器故障重构的新方法。该方法利用右特征结构配置设计的线性观测器来消除系统中的非线性以及干扰对故障重构的影响。这种设计不仅能够达到对故障的快速检测,而且能够准确地估计故障的大小。通过在某火箭姿态控制系统中的应用,证明了该设计方法的有效性和实用性。更多还原

【Abstract】 This paper presents a sensor fault reconstruction scheme.The scheme utilizes a linear observer designed by using right eigenstructure assignment so as to remove the effect of nonlinearities and disturbances on the fault reconstruction.The scheme not only can detect the fault as fast as possible,but also can estimate magnitude of the fault.The validity and practicability are proven by the using example in attitude control system of missile.更多还原
