摘要
智能灌溉中,灌溉液的离子浓度值(EC)的控制具有长时滞,大惯性的特点,并且受外界条件影响,对象增益变化剧烈。介绍了以EC值为控制对象的一种针对时滞、大惯性的非线性过程控制的解决办法———自适应模糊PID控制算法。
In intelligent irrigation, hydronium concentration great inertia, and due to the influence of the environment, value is studied, and a solution to the process control with trol method is introduced. of the solution has characteristics of long delay and the object plus varies a lot. The control of the EC delay and great inertia——adaptive fuzzy PID control method is introduced.
