智能自振荡自适应控制器的研究

Research on the Intelligent Controller Based on the Self-oscillatory Adaptive System

本文基于过程控制的特点，依据人工智能原理，将传统控制理论的一种被广泛应用但又缺乏深入研究的方法──自振荡自适应技术引入到过程控制中来，并配以具有知识处理、搜索和推理能力的智能模块。该控制器不仅能克服扰动、参数时变及纯滞后现象，而且能处理异常状态或克服对象动态特性的大范围变化，以保证系统长期运行的稳定性。

Based on the artificial intelligence theory, a design method of intelligent controller is proposed in this paper. The authors apply self - oscillatory adaptive technique to process control, a techniquewhich has been applied widely but hasn't been studied closely and add in intelligent model: knowledge processor, knowledge scouting and knowledge reasoning. This controller does not only overcome beunded disturbances and time - varying, decrease time - delays but also process the abnormal phenomenon and surmountlarge variation of plants' dynamic characteristic. Simulations show that it ensures good performance and robustness.
