Abstract :
The problem of directional residual generation in linear dynamic systems for fault detection and isolation (FDI) is addressed in this paper. The authors propose some extensions to a method first introduced by Gertler and Monajemy (1993) which uses the system-matrix defines by Rosenbrock (1970). A solution is given to the inversion problem of the system-matrix. The estimation of the fault parameters is then studied for different types of faults (sensor or actuator) An example of application illustrates the proposed approach
