Experiment Research on the Tractor Draught Control System and Discussion on the Judging Target System

To the tractor draught control system, a lot of indoor imination experiments were done. It was found that there were three parts of the frequency range of the system response, and there was a unresponsive range to the low amplitude draught disturbance. On this basis, the system character was analyzed. A new judging target system of the performance was presented.
