摘要
针对旋转闪蒸干燥机温度控制具有较大的滞后性、非线性和时变性的特点,以Φ1000型旋转闪蒸干燥机为具体对象,选用PLC作为温度控制器,并对其入口温度采用了自适应模糊PID控制算法。给出了闪蒸干燥机的具体结构及工作原理,根据其生产的实际情况和操作经验,总结出自适应模糊PID控制器的控制规则并确定了其相应控制参数。通过实际运行证明,本控制系统使其入口温度稳定在设定值附近,取得了较好的控制效果并确保了干燥质量达到生产指标要求。
Based on the characteristic of the delay, nonlinearity and time-varying in the temperature control system of spin flash dryer taking PLC as the temperature controller, the adaptive fuzzy PID control method is adopted to the entrance temperature of Φ1000 type spin flash dryer. The structure of spin flash dryer is given. According to the practice and experience, the control rules of adaptive fuzzy PID controller and its control parameters are determined. It is proved that the control system makes temperature steady near the enactment value in working, guarantees the dry quality reaching required production target.
