In view of the planting characteristics which are mainly consisted of small farmers and some large growing farmers in China, the solar energy technology was combined with spray irrigation technology together. In addition, a light and small solar energy canal feed sprinkler irrigation machine was developed. An autonomous navigation system was developed on selfdeveloped solar energy canal feed sprinkler machine. Under different working conditions, angle sensor and electronic compass were adopted for the autonomous navigation test. The precision irrigation control system and spraying domain control system were integrated to realize automatic control of sprinkler machine. According to the attitude information of the sprinkler machine acquired from angle sensor, electronic compass and wheel speed sensor, a fuzzy controller for autonomous navigation was built. By adjusting the speed of driving wheels on both sides, a closeloop feedback control system of steering was also built. Besides, to verify the navigation accuracy of the system, a tracking experiment was carried out. The results indicated that the lateral tracking error could be well eliminated with travelling speeds of 0.5m/min and 1.0m/min, which showed that the sprinkler machine was provided with high reliability and stability. In other words, the control system can well meet the demand of spraying work.
