In order to meet mechanical mining demand of China's thin coal seaming, the power electronics and motor control system in hardware and software integration is presented, which replace traditional variable-frequency system applied to mining, planning and transport occasions. Solving braking resistor large volume and heat dissipation problem of the variable frequency system is very necessary. Accordingly, energy feedback based on fuzzy PI control type system to replace the traditional energy consumption braking was designed in this paper. Through the system simulation, it is shown that this system has high power factor, small feed current harmonics and effectively absorb the feedback energy, especially can realize four quadrant operations.
