机械接触式导航控制系统的研究与试验

The Research and Experiment of Mechanical Contact Navigation Control System

研制了一种机械接触式导航控制系统,该系统利用Lab VIEW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 α and the steering wheel rotational speed 09 value according to the matching test. The system uses WP-500Y type high clearance spraying machine for field experiment carrier , the results show that when the steering wheel deflection angle is 0.115tad, the steering wheel rotation speed is 0. 357rad/s, the operation speed is 4km/h, the stability of the operation is the best.
