摘要: 以磨矿过程基础回路重要工艺参数——旋流器给矿浓度控制为研究对象，针对无模型自适应控制（MFAC）的参数自适应性差的问题，引入模糊控制，提出了模糊MFAC方法,给出了该方法的理论推导步骤,设计了模糊MFAC控制器。将模糊MFAC方法、基本MFAC方法和PID方法进行对比仿真实验，结果表明，模糊MFAC方法能够快速跟踪期望值，具有更小的超调量和跟踪误差，且抗干扰能力强。

Abstract: The paper took control of an important technological parameter namely hydrocyclone feeding concertration of grinding process basic circuit as study object, introduced fuzzy control according to bad parameter adaptivity of model-free adaptive control (MFAC), and proposed a fuzzy MFAC method. It gave theoretical derivation process of the method and designed a fuzzy MFAC controller. Compared with basic MFAC method and PID method, the simulation experimental results show that the fuzzy MFAC method can quickly track expected value with smaller overshoot and tracking error and has strong anti-interference performance.
