| Abstract: | The fault detectability condition of bilinear detection filter, a class of nonlinear system, is investigated. A detection filter is designed, and its fault complete detectability condition is obtained. The result indicates that, to make the system faults completely detectable, the system must be of the same number of sensors and independent system states as that of system faults. According to linear space characters, the result is correct. An example is presented for detection filter at last. |
