To realize an automatic turning control in a head-feeding combine at field ends under harvesting conditions, it is important to detect exactly the actual turning angle of the combine. This will minimize error in determining the turning angle that results from the skidding of combine tracks.
An angular rate sensor is used to detect the actual turning angles and these are integrated by a microcomputer. In order to reduce the calculation time, this system utilizes two microprocessors, one of which is used exclusively to calculate the turning angles and the other is used to control the whole system. In this paper, the turning angle control system is described and its performance is analyzed.
