Pesticide application control is the key technology to improve operation quality,reduce chemical pollution,and cut down costs of production.A control system of variable pesticide application machine hauled by tractor was designed based on AT89C52 using hysteresis control method.The system can automatically change spraying volume according to the speed of the tractor in order to stabilize pesticide application volume.Experiments show that:when the acceleration of the tractor is less than 0.4 m/s2,the error b...
