Abstract

A kind of product-truth-flowing fuzzy control algorithm is presented in this paper. Firstly, the steps of the algorithm are listed in detail. The algorithm holds advantage that fuzzy reasoning process is intuitionistic and its computation is simple. Secondly, based on the algorithm, a constant-temperature control system is designed with MAX7651 MCU, Pt100, MOC3041. Finally, practical control result shows that the performance of control system is excellent, its rise-time is about 21 minutes, the overshot of temperature is only 0.4 degC, and real-time temperature waves between -0.3degC and +0.3degC at expectation value.
