| 摘 要： | 研究基于Delta算子模型的离散时间系统故障检测问题.推导了Delta算子系统的故障可检测和可分离条件,给出了Delta算子模型的故障检测滤波器设计方法.研究表明,在采样周期很小时,Delta算子故障检测趋近于连续模型的相应结果,可统一处理连续系统和离散系统故障检测的相关问题.仿真实例验证了该方法的有效性.

| Abstract: | The problem of fault detection for Delta operator formulated discrete time system is studied.Some sufficient conditions are developed for fault detection and isolation(FDI) of Delta operator system.The design method of the Delta operator-based fault detection filter is proposed.When the sampling period is very small,the FDI method using Delta operator will approach the corresponding FDI results for continuous time cases,thus the related problems of fault detection for continuous time system and discrete tim... |
