摘要
球磨机负荷控制系统是一个具有大时滞、强时变性、强非线性及多变量与强耦合等特性的复杂系统。为了更好地克服球磨机负荷控制系统中存在的大滞后和不确定性等问题,提出了灰色预测无模型自适应控制(MFAC)策略。在控制系统下,分别采用PID、灰色预测PID、MFAC及灰色预测MFAC进行控制仿真分析。实际应用验证了该策略的可行性与合理性,表明了灰色预测无模型控制策略具有良好的控制性能和实用价值。
The ball mill load control system is a complex system featuring large time hysteresis, time - varying, strong nonlinearity, multivariableand strong coupling. In order to further overcome the large time lag and uncertainty and other problems of such load control system, the schemeof gray prediction model - free adaptive control (MFAC) is proposed. For this control system, PID, gray prediction PID, MFAC, and grayprediction MFAC are respectively applied in simulation analysis. The applications verify the feasibility and rationality of this strategy,and it is indicated that gray prediction model-free adaptive control has good control performance and practical value.
