Parameter Identification of Magnetorheological Damper Based on Modified Dahl Model
Based on the performance test results of the magnetorheological damper,a modified Dahl model was constructed in MATLAB/Simulink.The unknown parameters were identified using the parameter identification and curve fitting toolbox in MATLAB software to determine the relationship between each unknown parameter and the input current.Subsequently,an accu-rate magnetorheological damper model was built based on the identification results,and the experimental results were compared and verified against the simulation results.The results showed a high degree of fit between the simulation results and the experi-mental results,indicating that this identification method can establish a relatively accurate mechanical model of the magnetorheo-logical damper,laying the foundation for subsequent intelligent control design.
