摘要
针对工业过程控制对象,提出了带有前馈补偿的模糊控制的思想。结合传统模糊PID反馈控制器,利用模糊前馈控制补偿可测干扰对于系统输出的影响,同时提出模糊监督控制规则的概念,利用模糊监督控制克服系统中非最小相位环节的影响。将所提出的控制律应用于锅炉水位系统的控制,取得了令人满意的结果。说明了所提方法的有效性。
For process control plant, fuzzy control with feed-forward compensation is proposed. Combined with traditional fuzzy PID feedback controller, the fuzzy feed-forward control is applied to compensate the impact of measurable disturbance on system output. In the same time, conception of fuzzy supervising control is proposed, and corresponding supervising rules are formulated to attenuate the impact caused by non-minimal phase factor. The proposed method is applied to the control of boil water level with satisfactory results obtained, which justifies the feasibility of the proposed method.
