摘要
本文介绍了一种基于Atmega16单片机的模糊自整定PID调节器。该调节器采用模糊自整定方法整定PID参数,它能发挥模糊控制鲁棒性强、动态响应好、上升时间快、超调小的特点,又具有PID控制器的动态跟踪品质和稳态精度。同时,调节器具有显示温度、声光报警等功能。文章给出了参数自调整的原则、模糊控制算法,阐述了单片机参数自调整模糊控制器的工作原理,以及其硬件组成和软件功能,并提供了查表部分C51源程序。
This paper explains a PID regulator of fuzzy self-turning based on Atmega 16 MCU.This regulator adapts fuzzy parameter self-regulation method to further perfect the adaptive performance of PID control.This method can exert fuzzy control characteristics such as high robustness, good dynamic response, short rising time,smaU surplus and it possesses the dynamic track quality and steady precision of PID controller.The regulator has display,sound and flashes alarm functions.The principle of the parameter self-regulation is presented and a fuzzy control algorithm is given.The work principles and the compositions of software and hardware of the parameter self-regulation fuzzy controller with single chip microcomputer are discussed. The C51 program for lookup table was offered in this paper.
