Research of Hybrid Fuzzy-PID Control Technology based on the Temperature and Humidity Control

摘要

Aim at such drawbacks of conventional PID control as nonlinearity, time-change uncertainty, design depending on math model of controlled object, difficulty in PID parameter ascertaining, fuzzy technology is introduced into the conventional PID control in this study. Such hybrid fuzzy-PID control technology is applied in a container fruit process system for controlling its temperature and humidity, and application results demonstrate the efficiency and effectiveness of the proposed method.
