Identification of nonlinear model for rotary high aspect ratio flexible blade using free vibration response

Alexandria Engineering Journal, 2020
Nonlinear identification of a narrow cantilever blade undergoing free vibration was studied. In the absence of forced excitation and because of general data deficiency of this system, the current identification methods cannot be applied with sufficient ...

A tunable radial basis function model for nonlinear system identification using particle swarm optimisation

, 2009
A tunable radial basis function (RBF) network model is proposed for nonlinear system identification using particle swarm optimisation (PSO). At each stage of orthogonal forward regression (OFR) model construction, PSO optimises one RBF unit's centre ...
