Research on the Adaptive Cutting Method of Roadheader

Abstract:

The load on the cutting boom of roadheader changes violently because of the changes of rocks hardness. The power of cutter motor is related to the hardness of rock and propulsive force. The propulsive force is determined by the moving speed of cutting boom. The hydraulic control system of arcing cylinders is an electro-hydraulic proportional control system. The adaptive control model is build by Simulink. A PID control is used and the power of cutter motor is keep at a constant state by adjusting the speed of arcing cylinders.
