The invention belongs to the field of control, and provides a design method for a robust fault detection filter (RFDF) on the basis of a parameter-dependent Liapunov function method. A PDLF method is introduced into robust fault detection of a linear time-constant system with convex polyhedron non-determinacy. During processing of the RFDF design, the problem is distinguishing faults and other interference, which is remarkably different from robust analysis and control. An H_/H infinite normal form is adopted, which comprises two phases: (1) an optimal RFDF design method of a residual error generator with certain interference attenuation and maximum fault sensitivity, and (2) a method for designing a threshold value for a residual error generated by estimation.
