| Abstract: |
| This paper is aimed at analyzing the identification precision of the finite impulse response (FIR) function models of discrete-time control systems under the pseudo-random invert-repeated m-sequences stimulation1 An explicit formula of the correlation identification precision is given in the face of colored noises. Two simulation examples are cited to support the analyses. |
| Keywords: FIR model correlation identification pseudo-random sequence precision analysis |
