摘　　要：提出了一类乘积型真值流动模糊控制算法.该算法具有推理直观,计算简单的优点.采用MAX7651、Pt100、MOC3041等器件设计了基于此算法的恒温控制系统.实验结果表明,基于此算法的控制系统性能良好,上升时间约21min,温度超调仅为0.4℃,在期望值附近的波动范围小于±0.3℃.A kind of product-troth-flowing fuzzy control algorithm is presented in this paper. The algorithm holds advantage that fuzzy reasoning process is intuitionistic and its computation is simple. Second, based on the algorithm, a constant-ternperature control system is designed with MAX7651, 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℃, and real-time temperature waves between - 0.3℃ and ＋ 0.3℃ at expectation value.
