Abstract:

In traditional parity space approaches, a parity vector with a low order means a simple online realization but a bad performance, while that with a high order leads to a good performance but an unacceptable calculation amount. In this paper, by introducing a simple scalar IIR (Infinite Impulse Response) filter, a new kind of parity relation based residual generator and the corresponding optimization approach are proposed. With the new approach, a residual generator can deliver a very good performance index but with a parity vector of low order. Simulation results are given.
