Design of Embedded MRFD Controller

Abstract:

Article Preview

According to the particularity of magnetorheological fluid (MRF), provided the design project of embedded magnetorheological fluid damper (MRFD) controller based on ATmega8. The controller adopted Buck converter to achieve input\output power conversion. The feedback loop used voltage and current double feedback adjustment to control PWM drive circuit, so that adjusted the output of Buck converter. According to the set value, the MRFD controller outputted the matching value by the high frequency PWM output. The testing of output responding time was done. The results show that MRFD controller has much higher reliability and faster responding, satisfying the using demand of MRFD.
