from N samples ~l~(kT\), yL(kT,) (k = 0, 1,. , N 1) of the low-pass-filtered input u,(t) and output yL(t) signals (7; is the sampling period). Correct handling of the time derivatives in the differential equation (1) is the basic problem of parameteric continuous-time system identification. Several solutions have been proposed, all of which explicitly or implicitly reconstruct the time derivatives of the sampled continuous-time signals involved (Sinha and Rao, 1991). A first possibility… CONTINUE READING
