Analysis and mitigation on conducted electromagnetic interference of semi-active control strategy for magneto-rheological damper

Abstract

The controllable magneto-rheological damper has been widely used in vibration mitigation system, such as vehicle suspension and aerospace landing gear, which is subjected to the direct magnetic field based on the magneto-rheological damper controller under semi-active control strategy. Due to the displacement vibration and semi-active control strategy, conducted electromagnetic noises are generated through the power supply. In the paper, the conducted electromagnetic interference noise mechanism and model are proposed for the magneto-rheological damper with semi-active control strategy based on the theoretical and simulation analysis. Then, a novel smoothing algorithm is designed to reduce the above conducted electromagnetic interference noises. The simulation and experiment results show that conducted electromagnetic interference noises can be suppressed 2-8 dBμ V by employing the present smoothing algorithm and comply with EN 55022, thus it can support the development, application and safety & electromagnetic compatibility design for the MRD device.
