研制了一种机械接触式导航控制系统，该系统利用LabVIEW 编程，采用PID控制方式进行对行调节，根据自动对行作业的具体需要，设计了机械接触式导向机构，并通过匹配性试验确定了转向轮偏转角度α与转向轮转动速度ω的取值。该系统以 WP－500Y 型高地隙喷药机为载体进行田间试验，结果表明：转向轮偏转角度为0．115rad、转向轮转动速度为0．357rad／s、作业速度为4km／h时，自动对行作业稳定性最好。“,”This paper develops a mechanical contact type navigation control system .The system uses LabVIEW program-ming, uses PID control method to adjust the line ,designs mechanical contact type guide mechanism According to the spe-cific needs of the automatic operation of the line , determines the steering wheel deflection angle αand the steering wheel rotational speed ωvalue according to the matching test .The system uses WP-500 Y type high clearance spraying machine for field experiment carrier , the results show that when the steering wheel deflection angle is 0.115rad, the steering wheel rotation speed is 0.357rad/s, the operation speed is 4km/h, the stability of the operation is the best .
