摘要
转向操纵控制系统执行效果的优劣决定了导航车辆工作的准确性和稳定性。为此,以试验的方法对现有导航系统中转向操纵控制平台进行硬件测试、角度传感器标定、步进电机测试和角度传感器精度测试试验,提出从硬件上提高精度的方法。同时,根据转向操纵控制器中执行机构步进电机存在的小角度难以响应的问题,进行了控制电路设计和仿真,实现了对小角度信号的快速响应,为提高导航操纵控制器精度提供了思路。
The merits of the steering control system executed effect determines the navigation accuracy and stability of the vehicle work. This paper introduced the experiment method of existing steering control platform in the navigation system hardware test. Angle sensor calibration experiment,stepper motor test and angle sensor precision test are designed and conducted. Improve the precision of factors from the view of hardware is put forward. At the same time we performed the control circuit design and simulation for the difficult to response to the problem of small angle in stepper motor which is steering control actuators. The test achieved the small angle signal of fast response,provided ideas for improving accuracy of navigation control controller.
