Abstract

Electrodynamic vibration shaker is the key equipment in vibration and shock environmental experiment, and model identification and estimation for the shaker are the necessary procedure for developing the research on vibration control technology and simulation technology. Basing the dynamic and electrical coupling model of electrodynamic vibration shaker, the system identification and parameter estimation method which taken the shock signal as motivation is proposed. The regulated shock waveform was achieved by using calculated model parameters accurately. The results showed the validity and feasibility of the model identification method by comparisons simulation results with experimental results.
