摘    要:根据风面控制系统的时滞与不确定等特性,采用改进混沌优化算法与智能PID控制算法,设计并实现一个实用的智能风面控制系统。先通过智能PID控制算法较精确地控制风机输出风速,并再在此基础上引入曲度的概念来描述风道内风面的弯曲程度,通过改进混沌优化算法在输出风速的邻域内搜索最佳曲度来优化输出风速,实现风面的均匀性控制。现场应用结果表明,该算法具有较好的鲁棒性和抗干扰能力。

Abstract: According to the characteristics, such as delay and uncertainty, of air speed plane control system, the improved chaos optimization algorithm and intelligent PID control algorithm were adopted to design and achieve a practical intelligent air speed plane control system. Firstly, by using intelligent PID control algorithm, the output speed of the fan could be relatively precisely controlled. Then, based on these results, the concept of curvature was introduced to describe the curvature of the air speed plane in the duct. And by making use of the improved chaos optimization algorithm, better curvature could be found in the neighbourhood of the output speed to optimize it. So, the homogeneity control of the air speed plane could be implemented. It is demonstrated by the field application results that the algorithm has good robustness and anti-interference ability.
