The Reactor Intelligent Controller For Research And Development

Reactors are one kind of important vessels in chemical production. The reaction mechanism in it is complicated. Because of multiple controlled objects and big time-variant, non-linear, time-delay, classical control theory and optimal control of modern control theory are not fit for the control of reactors.The analysis of the reactors' heat transfer characteristics, and the transfer function of cooling mixture's flux to the temperature in reactors are concluded in the paper. Intelligent control system of two-part control according to error range is designed also. Adaptive fuzzy-control based on modified rule and incomplete differential PID-control are adapted in the system. The analysis process and control algorithm are described in detail.On the basis of this, intelligent controller based on series of MCS-51 single-chipcomputer is designed, and popular serial bus------I~2C bus and 1-wire bus are used in thispaper, which constitute the system of multiple points temperature measurement. Port circuits of single-chip computer and software program are designed in the paper, too. By controlling the executive device and condition parameters of the reactor, the control of temperature and its grade realized.
