摘　　要：针对模糊控制的不足和PID控制的缺点,提出铁观音茶烘焙机模糊-PID分段控制策略,综合了模糊控制和PID控制的优点,对传统模糊控制方法与PID参数整定进行了改进,使得系统在小超调的情况下获得最短的温度调节时间.仿真与试验结果表明该控制器设计方法简单实用,具有良好的控制效果.As regards the disadvantages of fuzzy controller and PID controller,a fuzzy-PID control strategy was brought forword for Tieguanyin tea roaster temperature control system,which can achieve the least regulate time on the condition with small-overshoot to control temperature intelligently.The traditional fuzzy control method and PID parameter tuning has been improved.The method combines fuzzy control technology with PID algorithm and applies the multi-mode control to design a control system of temperature.Result shows that the control system is effective in controlling the plant with multi-variable,highly-coupling,long-dead-time and has ideal characteristics of small overshoot,fast regulation and short climbing time and good robustness.
