Abstract

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.
