模糊PID控制在轮式机器人直立系统中的应用
Application of Fuzzy PID Control in Upright Wheeled Robot System
摘要
Abstract
Erect wheeled robot which has simple structure,strong controllability,low cost,fast speed,flexible control and other characteris-tics,is widely used in mobile robot needing a predetermined path. According to wheeled robot modeling,the control algorithm of robot’ s wheel acceleration in upright condition is obtained,and the membership relations of the fuzzy self-tuning PID controller and fuzzy rule table is designed. Comparison with Simulink simulation indicates that the fuzzy PID self-tuning algorithm is superior to the conventional PID algorithm. The two algorithms are used in the process of the robot vertical control,measuring the output curve of z axis under condi-tion of vertical angular acceleration magnified 1 000 times,calculated that the variance shrinks by 73. 4%,range shrinks by 67. 5%,and comprehensive performance improves three times after a blurring. It verifies that upright control effect is better than conventional PID after the fuzzy self-tuning.关键词
