| Abstract: | Automatic control of ploughing depth of tractor with servo valve according to the load and ploughing depth is presented in detail. The meassures are that the signals of displacement transducer of ploughing depth and force transducer of ploughing resistance are piled up and compared with given ploughing depth,and then inputted to servo amplifier, and exported controlling signals that control the electric-liquid servo valve,therefore the travel and direction of controlling valve will be changed and the oil quality of raising oil jar of tractor will be changed. The aim to change ploughing depth is achieved. Successful control system and field test with the TMD-model of servo control system of tractor ploughing depth have been made and satisfactory results have been obtained. |
