摘要:

以颜料在聚丙烯内的分散性实验为例,探究了处于不同环境下的间歇式混合器比例-积分-微分控制(PID)温控系统的加热效果,并以密闭室温环境下的混合器温控效果为基准,结合PID参数对该温控系统效果的影响制定了相应的模糊规则,将模糊算法与PID算法相结合,建立了一种基于模糊PID算法的温控系统,并详细阐述了建立过程。结果表明,该模糊PID温控系统能够实时的调节PID参数,有效地提升了混合器的加热效率,提高了颜料分散性实验结果的准确性。

Abstract:

Taking the dispersion experiment of pigments in polypropylene as an example, the heating effect of PID temperature control system of batch mixer in different environments was investigated. Based on the temperature control effect of mixer in closed room temperature environment, the corresponding fuzzy rules were constructed by a combination with the influence of PID parameters on the effectiveness of temperature control system. A fuzzy P?based temperature control system was then established by combining the fuzzy algorithm and PID algorithm. The temperature control system of ID algorithm and the establishment process were described in detail. The experimental results indicated that the fuzzy PID temperature control system could adjust the PID parameters in real time, effectively improved the heating efficiency of the mixer under the interference of external environment, and significantly improved the accuracy for the results of the pigment dispersion experiment.

Key words: fuzzy proportion-integral-differential contral algorthm, environment condition, temperature control system, intermittent mixer, pigment dispersion experiment
