Embodiment 1
[0052] A switched reluctance motor open winding control system 100, such as figure 1 As shown, including: controller, current sensor, position sensor, and open winding inverter;
[0053] The controller is used for receiving and based on the three-phase current feedback value of the switched reluctance motor collected by the current sensor and the speed feedback value and position feedback value of the switched reluctance motor collected by the position sensor, and adopts an AC motor speed-current double closed loopVector control method, controlling the open-winding inverter to generate bipolar sinusoidal current with DC bias;
[0054] Open-winding inverter for injecting bipolar sinusoidal current with DC bias into a switched reluctance motor.
[0055] It should be noted that the current sensor is used to detect the corresponding three-phase current on the three-phase stator winding of the switched reluctance motor; the position sensor is used to detect the mechanical speed a...
Embodiment 2
[0103] A switched reluctance motor open winding control method 200, such as Figure 5 shown, including:
[0104] Step 210, collecting the speed feedback value, position feedback value and three-phase current feedback value of the switched reluctance motor in real time;
[0105] Step 220: Based on the given rotational speed value, rotational speed feedback value and position feedback value, two PWM control signals are obtained by adopting the AC motor rotational speed-current double closed-loop vector control method;
[0106] Step 230 , based on the two PWM control signals, drive the open-winding inverter to generate a bipolar sinusoidal current with DC bias and inject it into the switched reluctance motor to complete the open-winding control of the switched reluctance motor.
[0107] The analysis of related technical solutions such as bipolar sinusoidal current with DC bias, open-winding inverter, and two PWM control signals is the same as that in Embodiment 1, and will not be ...

technical field [0001] The invention belongs to the technical field of motor drive control, and in particular relates to a switched reluctance motor open winding control system and control method. Background technique [0002] With the development of my country's industry and manufacturing industry, energy issues have become a hot spot of social concern, and the use of clean new energy is imperative. Electric energy has played an important role in replacing fossil energy in various aspects such as industrial production and transportation. Among them, the motor, as the most critical component in electromechanical energy conversion, plays an irreplaceable role in the industrial application of electric energy. Compared with the internal combustion engine, the motor has a series of advantages such as flexible control, less pollution, and less vibration and noise. Therefore, the application of the motor has attracted widespread attention. [0003] In the motor drive system, the ...
