Abstract
Chapter 3 describes, for LTI systems, data-based or nonparametric identification methods that directly provide estimates of the impulse response function g(t) in the frequency domain, G(ejω). In particular, the empirical transfer-function estimate (ETFE) and the critical point identification method are introduced. The frequency domain descriptions, given an estimate of the frequency function G(ejω), are particularly suited for classical and robust controller design.
