Abstract
In mechanical drive systems, existing resonance suppression strategies and autotuning methods often rely on accurate system models. This paper completely describes a non-parametric method to realize the identification of resonance/anti-resonance frequency and characteristic peaks. First, the settings of the excitation signal and loop configuration are discussed. Correlation analysis method is adopted for data processing. After filtering, the resonance/anti-resonance frequency and characteristic peaks are determined through the combined analysis of magnitude and phase frequency characteristics. The results of experiment show that this method can effectively identify the resonance/anti-resonance frequency and non-mechanical properties.
