    摘要:

    構(gòu)建了自動(dòng)導(dǎo)航模糊控制器,并詳細(xì)闡述了基于模糊控制的自動(dòng)轉(zhuǎn)向方法。在改裝的電瓶車上,開發(fā)了基于DGPS、電子羅盤和角度傳感器的自動(dòng)導(dǎo)航控制系統(tǒng),并論述了其結(jié)構(gòu)和工作原理,提出了直線跟蹤和曲線跟蹤的方法,使用簡化的二輪車運(yùn)動(dòng)學(xué)模型進(jìn)行了仿真,并進(jìn)行了直線跟蹤和曲線跟蹤試驗(yàn)。仿真和試驗(yàn)結(jié)果表明,此導(dǎo)航控制系統(tǒng)可以有效地控制電瓶車按預(yù)定的路徑行走。當(dāng)速度為1m/s,直線路徑跟蹤時(shí)的最大偏差為0.19m;當(dāng)速度為0.8m/s,曲線路徑跟蹤時(shí)的最大偏差為

    Abstract:

    0.26m。The method for fuzzy control steering and the construction of fuzzy controller were described in detail at first. On a refitted storage battery car, an automatic navigation control system was developed with DGPS, digital compass and angle sensor. The construction and work principle of the navigation control system were introduced. Line path tracking and curve path tracking methods were brought forward. At last simulation was taken using kinematics of two-wheel vehicle, at the same time line path tracking and curve path tracking experiments were conducted. Results of simulation and experiments indicate that navigation control system can make the vehicle run following the predefined path. The lateral error is less than 0.19m when the car ran following the predefined line route, and the lateral error is less than 0.26m when the car ran following the predefined curve path.
