摘要： 本文主要对基于制动控制器的磁流变制动器性能进行探究.对磁流变制动器进行结构设计和仿真优化，得出制动器的最优结构，并基于Arduino开发板与L9349功率驱动芯片设计了磁流变制动控制器.为探究基于制动控制器的制动器制动性能，分别进行了不同阶跃信号规律、正弦信号规律的制动力矩跟随实验和制动减速度实验.实验结果得出制动器的响应时间约在40ms，控制系统滞后时间约为70ms，制动力矩在跟随过程中滞后时间约为20ms，与液压制动系统相比具有较快的制动响应.本研究对磁流变制动器的发展和应用奠定了基础.

Abstract: The braking performance of MRB(magneto-rheological brake)based on braking controller was mainly explored in this paper. The main research contents included design and structural optimization to obtain the optimum MRB. In order to study its braking performance，the MRB controller was designed based on the Arduino board and the L9349 power driver IC. Deceleration experiment and braking torque following experiment with different step signals and sine signal were carried out for exploring braking performance. The results indicate that the MRB′s response time is about 40ms，the delay time is about 70ms，and the lag braking time is about 20ms in the following process that was faster than that of the hydraulic braking system. This study may has great significance with laying a foundation for the development and application of MRB.

Key words: magneto-rheological brake, structural optimization, controller, braking performance, response time
