Abstrakt: It is shown how diagnostic residuals, which exhibit directional properties at all times in response to an arbitrary mix of input and output faults, can be generated using dynamic parity equations. The residual generator is obtained by applying a transfer function type tranformation to the dynamic input-output model of the monitored plant. It is also shown that the residual generator is polynomial (moving average) if the specified fault responses contain the invariant polynomial of the fault system.
