Abstract
According to the characteristics of mine fanner, the running characteristic and requirements of load was analyzed, and the fanner control system was simulated by using frequency control technology in this thesis. The speed flux double closed loop vector control system was designed by using the principle of the rotor field-oriented vector control and the mathematical model of asynchronous motor. The simulation model was simulated and analysised by MATLAB/Simulink. The result indicated that the vector control system can not only quickly responded to the change of the load torque but also have good speed control performance, and the mine fanner operation requirements was satisfied.
