单输入模糊控制在液位控制系统中的应用

本文提出一种利用复合结构终端滑模面作为输入的单输入模糊控制器设计方法,将这种控制方法应用于液位控制系统,取得了满意的控制效果.单输入模糊控制器规则数比普通模糊控制器大大减少,这样就使得模糊控制器的设计和调节更简单、更方便.同时这种模糊控制器由于具有准滑动模态的性质,体现出较好的鲁棒性和稳定性.通过对水箱的控制实验,结果表明,该方法在实践过程中是切实可行和值得推广的.

Application of Single Input Fuzzy Controller in Liquid Level Control System

A simple but powerful FLC (Fuzzy Logic Controller) design method in put forward by using sliding mode switching surface as a sole fuzzy input variable. It achieves good performance for liquid level control. The total number of rules of the single input fuzzy controller is greatly reduced compared to conventional FLC. The design and tuning of controller are more simple and easy. At the same time this kind of fuzzy controller is equivalent to the quasi-sliding mode controller, so the robust property and stabi...
