Query: Identification of Self-Excited Systems Using Discrete-Time, Time-Delayed
  Lur'e Models   This paper presents a system identification technique for systems whose
output is asymptotically periodic under constant inputs. The model used for
system identification is a discrete-time Lur'e model consisting of
asymptotically stable linear dynamics, a time delay, a washout filter, and a
static nonlinear feedback mapping. For all sufficiently large scalings of the
loop transfer function, these components cause divergence under small signal
levels and decay under large signal amplitudes, thus producing an
asymptotically oscillatory output. A bias-generation mechanism is used to
provide a bias in the oscillation. The contribution of the paper is a
least-squares technique that estimates the coefficients of the linear model as
well as the parameterization of the continuous, piecewise-linear feedback
mapping.
