Simulation Results

Bouc-Wen model is a kind of more representative differential hysteretic model, which has the advantages of strong universality and parameters easily identification and that can better approximate the hysteresis curve. By using nonlinear system dynamics circuit theory, Bouc-Wen mathematical model is transformed into circuit model, the simulation results test the validity of the designed circuit and a physical circuit board is finally made. An experimental setup is established with the data acquisition card and related software. Circuit debugging and signal output under typical excitation of the circuit board are performed, the results show that the circuit board is be feasible to demonstrate the Bouc-Wen model.
