Abstract: Coal mine environment need to be simulated in development process of belt conveyor control system. For high cost of building physical environment wihch was the same as coal mine environment in laboratory, a hardware in the loop simulation test system for belt conveyor control system was designed. Combining with configuration parameters such as driving mode and driving device of belt conveyor, control strategy of belt conveyor control system is carried out by collecting running status of belt conveyor, environment parameters and transportation condition simulated by hardware platform. According to control input of belt conveyor control system, running status of belt conveyor is iterated through dynamic model of belt conveyor, and iteration result is fed back to belt conveyor control system through the hardware platform, so as to realize closed-loop feedback control and performance verification of belt conveyor control system. The simulation test result verifies validity of the system.
