Magneto-Rheological Vibration Reduction Control and ARM Realization

摘要

The magneto-rheological (MR) vibration reduction control technology is studied and a design and implementation of an automobile MR vibration reduction control system based on ARM9 is given in this paper. This paper introduces the system design process of embedded controller, current driver and other hardware, system software structure. Design of real time control system can realize the multi-channel vibration signal acquisition, control algorithm, CAN communications and other functions. The simulation and experiment show that, the control system software and hardware design can meet the functional requirements and have the advantages of fast response, high control precision and working stability.
