The turning angle control system which was discussed in the Part 1 was applied to the turning control at field ends and the shortest path control. The turning control at field ends was realized by a microcomputer based on programmed control system with feedback of actual turning angle. The shortest path control was devised to improve the working efficiency. First, the steering angle and time between each steering are measured by the angular rate sensor, and the winding data of the row of paddy rice are collected. Second, the shortest path of combine is calculated from these data and the automatic steering control is done along the path.
In this paper, the above control are described and their performance are analyzed by actual field experiments.
