Abstract :
Recently, identification of real-valued NMP zeros of discrete-time LTI systems has been studied in a few works. Among the key results, an adaptive input design approach is presented for consistent estimation of NMP zeros of stable LTI systems. However, this result is not applicable if the sign of the first impulse response coefficient is unknown. This paper studies the problem of estimation of the farthest NMP zeros without such prior knowledge.
