摘要
主要研究磁流变阻尼器驱动电流源的设计和实现。通过PSpice仿真分析了电流响应速度和控制精度的影响因素。介绍了自行研制的基于单片机C8051的数字型PWM电流源和TL494的电压型PWM电流源。并根据实际设计过程中得到的经验对磁流变阻尼器驱动电流源的设计提出了一些建议。
This paper mainly concerns on the design of the current source of the magnetorheological fluid damper （MRFD）. The influence factors to the manipulative performance of power （linearity, relative error, response time） are emulated and analyzed by PSpice. And two kinds of PWM power are introduced： voltage PWM with TL494C and digital PWM with c8051. And some advices to design of the current source of the MRFD are given.
