Abstract

The Fast Fourier Transform (FFT) and the harmonic balance nonlinearity identification were applied for the parametric identification of nonlinear system with parameter excitation. the error analysis and the parameter identification for Mathieu-Duffing equation with periodic, period-doubling and chaotic responses were studied by using the numerical simulation. The results indicate that the parameter identification using the proposed method is not only precise and prompt, but also effective for the system operation in non-period state.
