摘要：
The harmonic probing algorithm allows the generation of frequency response functions (FRFs) from discrete-time system models. If the model is non-linear, the higher-order FRFs or Volterra kernel transforms can be obtained. The object of this paper is to supplement the algorithm with a procedure for estimating confidence bounds for the FRFs. A Monte Carlo approach is used, and the procedure is illustrated on models produced from simulation and from an experimental data set. (C) 1998 Academic Press.
