针对连铸机结晶器液位控制系统中一些常用控制方法无法克服由拉速剧烈变化或其它扰动构成的有色噪声的影响这一实际问题，在已有模型的基础上建立了一种包含有色噪声的更为简单实用的模型，同时将基于此模型的一种能克服有色噪声扰动的广义预测控制方法用于结晶器液位控制。实验结果表明，采用该方法后结晶器液位偏差较小，系统鲁棒性大大改善。 In view of the fact that some commonly used control methods in the liquid level control system of continuous casting machine can not overcome the influence of colored noise caused by drastic change of pulling speed or other disturbances, a new method based on the existing model is established, A more simple and practical model, and a generalized predictive control method based on this model to overcome the colored noise disturbances is used in the mold level control. The experimental results show that the liquid level deviation of this method is small and the system robustness is greatly improved.
