Direct torque control system for open-phase compensation of six-phase motor

The invention discloses a direct torque control system for the open-phase compensation of a six-phase motor, and the system comprises an AC power supply, a rectification module, an inversion module, an IGBT drive circuit, a Hall current sensor, an encoder, a motor, an encoder, an analog circuit interface, an FPGA, a DPS, and a PC. The AC power supply is connected to the input end of the inversionmodule through the rectification module. The output end of the inversion module is connected with the motor, the motor is connected with the encoder, the encoder is further connected with the DPS, theHall current sensor is connected to a circuit between the inversion module and the motor, and the Hall current sensor is further connected with the DSP through the analog circuit interface. Accordingto the direct torque control system for open-phase compensation of the six-phase motor, a open-phase five-phase permanent magnet synchronous motor is controlled by adopting a carrier type PWM methodbased on effective action ti
