基于模糊控制理论的PID闭环控制系统的研究与设计
Research and design of PID closed-loop control system based on fuzzy control theory
摘要
Abstract
To satisfy the various complex control tasks,adapt to the ever-changing market environment,and accomplish a variety of industrial control requirements rapidly and accurately,a PID closed-loop control system based on fuzzy control theory was researched and designed. The system design is based on PID algorithm principle. Digitization is taken as the implementation method. The parameter self-tuning of PID control system is realized by means of the fuzzy control theory. A corresponding RC first-order circuit hardware debugging platform was established during the research to fulfill the debugging of PID closed-loop controller and realize associative functions of PID control system based on the fuzzy control theory. The high-precision AD/DA convertor is used in test process to ensure the accuracy requirement of digital system,which can improve the feasibility and va-lidity of the system. The experimental results show that the PID closed-loop control system can meet the requirements of various industrial control,and has strong practical significance.关键词
