摘要
理论分析磁粉制动器的低速爬行现象，探讨低速稳定性条件、用扭矩反馈控制制动器的激励电流来消除爬行的产生。在PID控制原理的基础上提出PIDD控制算法能有效消除低速爬行，保持低刚度系统中磁粉制动器低速稳定性。
The creep phenornenon of dry powered brake at low speed is analyzed and the stability coriditiori at low-speed discussed theoretically iri the paper. The creep can be eliminated via the adjustmerit of the activating current of the brake with torque feedback control.Based on the PID coritrol principle, a control formula called PIDD is presented. PIDD is able to effectively elimiriate the creep phenomenon at low speed arid keep the stability of the dry powered brake at low speed iri the low stiffness mechanical system.
