Abstract: Mixing-loading truck has the advantage of safety and high efficiency, so it has been widely used in engineering explosion.For the requirement of high precision and reliability in the heavy ANFO explosive production, a novel control system of mixing-loading truck of heavy ANFO explosive is designed.The system uses a special FUZZY-PID control algorithm for the closed loop control of the flow of the raw materials, which improve the quality of the product and increase the efficiency of the system significantly.

Key words: Mixing-loading truck, Fuzzy-PID control, Flow control
