摘　　要：针对磁粉制动器在扭矩加载时,由于磁阻的磁滞、磁通的饱和性和磁导率的非恒定性,造成的加载精度低和系统响应滞后等问题,对磁粉制动器加载控制方法进行了研究,使用Matlab/Simulink设计了一种模糊自适应PID控制器,利用模糊规则在线对PID参数进行了优化调整,并对蜗轮蜗杆减速器扭矩加载系统中磁粉制动器的加载特性进行了仿真和实验。研究结果表明,模糊自适应PID控制器在磁粉制动器加载系统的控制中,大大提高了磁粉制动器的加载精度,且明显减小了系统响应的时间,表现出了良好的自适应性和稳定性,能够用来实现对磁粉制动器加载系统的有效控制。Aiming at problems of the magnetic powder brake in torque loading system,such as the loading precision is not high enough and the response time is not fast enough,because of the hysteresis of magnetic resistance,saturation of magnetic flux,Non constancy of magnetic conductivity. The self-adaptive fuzzy PID controller is studied by matlab / simulink that applicants in worm reducer loading system. It is used to optimize the parameters of PID online. By the test,the results indicate that the self-adaptive fuzzy PID controller can improve the loading precision and reduce response time of the system. It also has good adaptability and stability,and can be used to realize effective control of the loading system.
