均质机复合温度控制系统的设计

Design of Composite Temperature Control in Homogenizer System

温度控制作为均质机控制系统的关键环节,其控制质量的好坏直接影响均质产品的乳化程度;均质机温度控制过程是一个具有大时滞、非线性、强干扰的复杂控制对象,采用常规的PID控制技术对温度进行精密控制难以取得理想效果。针对这一问题进行研究分析,提出了一种基于复合模糊PID算法的智能控制方法。研究结果表明,新的控制方法能够有效地提高控制精度,具有较好的动态性能和较强的鲁棒性。

Temperature control is the key to the homogenizer control system.Its controlling quality has immediate influence on the quality degree of emulsion treatment.Homogenizer composite temperature control is a complicated process with difficulties like serious nonlinearity lagging and strong jamming in the part way.This paper introduces a new control method which can increase the accuracy effectively and has the good dynamic property and the strong robustness.
