摘　　要：本文基于未知输入观测器，针对含有未知输入干扰的不确定动态系统，提出一种故障检测的新方法．本文提出的方法与其它方法如特征向量配置法相比，具有条件要求较低，设计简单的优点．Based on a recently developed approach to the design of unknown input observers,the paperpresents a fault detection method for systems with unknown inputs. Compared to the conventional methodusing eigenstructure assignment,the approach discussed in this paper has the advantage of simplicity andrequires less conditions.
