【摘要】 提出了一种基于广义坐标变换的线性时滞系统故障诊断设计方法.主要设计思想是通过广义坐标变换将系统的状态时滞、输出时滞由输出项来替代表示,构造观测器产生残差,进一步将残差系统表示为LTI的形式,然后采用LTI系统中成熟理论进行时滞系统故障诊断设计.最后的仿真实验验证了该方法的有效性.更多还原

【Abstract】 Proposed a generalized coordinate change based approach to the fault detection design for time delay systems.The key of the design is that the time delay terms in the output and state are injected by the system’ s output through generalized coordinates transformation.An observer is constructed to generate the residual and the residual system could be formulated in LTI form,then the FDI for the time delay systems could be designed using the well-known methods in the LTI systems.The applicability of the presented scheme is illustrated by a numerical example.更多还原
