基于模糊PID的浓盐水液位控制器的设计

摘要

Taking into account of the characteristics of seawater desalination control sys-tem, a new Fuzzy-PID controller combining intelligent control with traditional control was in-troduced to solve the problem of slow response speed and large overshoot occurring during the actual control process of strong brine level by existing PID control system. The new sys-tem has also improved the stability and control accuracy of the whole desalination system.%结合海水淡化控制系统的控制特点，引入智能控制结合传统控制组成新型模糊PID控制器，来解决现有PID控制系统在实际控制浓盐水液位过程中出现的响应速度慢、超调量大等问题，同时提高了整个海水淡化系统的稳定性和控制精度。
