基于模糊PID控制的AVR单片机温度控制性能研究

本文介绍了一种基于AVR单片机的温度模糊自适应整定PID控制系统,该系统充分利用了AVR单片机运行速度高、中断响应快、功耗低、可靠性高等优点。对于一般温度控制环节存在的非线性、大滞后以及时变性等问题,该系统提供了较为理想的解决方案,将模糊控制引入到传统PID控制中,既达到PID控制精确、静态误差小的目的,又能够保证模糊控制自适应性强、鲁棒性好、稳定性高的特点,改善了温度控制系统的动态性能。

Research on AVR SCM Temperature Control Performance Based on Fuzzy PID Control

This paper introduces a PID control system based on AVR SCM temperature fuzzy adaptive tuning;the system makes full use of the advantages of AVR SCM such as high running speed,fast interrupt response,low power consumption,and high reliability.For characteristics existing in common temperature control link such as the nonlinear,large time delay and time varying nature,this system provides a comparatively ideal solution.Fuzzy control introducing to the traditional PID control can not only achieve the goal of PID precise control and small static error,but also ensure that the fuzzy control＇s characteristics of strong adaptability,good robustness,and stability high,so as to improve dynamic performance of the temperature control system.
