A frequency control system of electrically excited synchronous motor based on the air-gap flux oriented was studied for the high-performance control mine hoist. The vector control theory based on the air-gap flux oriented was described. The frequency control system of electrically excited synchronous motor was showed. Three commonly used mathematical models of the air-gap flux observer were given and analyzed. The hardware control system of electrically excited synchronous motor based on DSP and FPGA was designed. This system has a high degree of digitization and it can achieve high- performance and high-reliability control for the electrically excited synchronous motor.
