摘　　要：针对重介质选煤系统具有强耦合、非线性、多变量的特点,利用传统PID算法存在超调量大的问题,提出了一种基于CMAC与PID算法的控制方法。通过研究介质密度与介质桶液位的动态特性建立了重介选煤系统的数学模型,给出了CMAC与传统PID算法相结合的控制原理。Simulink仿真结果表明,该方法优于传统PID算法,动态性能好,稳态精度高。For problem of big overshoot of PID algorithm used by heavy medium coal preparation system which has characteristics of strong coupling,nonlinear and multivariate,the paper presented a control method with CMAC and PID algorithm.Through researching dynamic characteristics of medium density and liquid level of medium bucket,it established mathematical model of heavy medium coal preparation system and gave control principle with the CMAC and traditional PID algorithm.The Simulink simulation result showed that the control method is better than traditional PID algorithm,and has good dynamic performance and high stability level.
