精选示例

Use Motor Control Blockset™ to generate a Simulink® model that is configured for a specific hardware and motor control technique.
使用基于 STM32 处理器的板对三相 AC 电机进行开环控制
此示例使用开环控制（也称为标量控制或伏特/赫兹控制）来运行电机。这种方法会改变定子电压和频率来控制转子转速，而不使用来自电机的任何反馈。您可以使用这种方法来检查硬件连接的完整性。开环控制的恒速应用使用固定频率的电机电源。开环控制的可调速应用需要可变频率电源来控制转子转速。为了确保恒定的定子磁通，请保持电源电压振幅与其频率成比例。

Field-Oriented Control of PMSM with Hall Sensor Using STM32G4xx Based Processors
Implements the field-oriented control (FOC) technique to control the speed of a three-phase permanent magnet synchronous motor (PMSM). The FOC algorithm requires rotor position feedback, which is obtained by a Hall sensor.
Hall Offset Calibration for PMSM with STM32 Processors
Calculates the offset between the rotor direct axis (d-axis) and position detected by the Hall sensor. The field-oriented control (FOC) algorithm needs this position offset to run the permanent magnet synchronous motor (PMSM) correctly. To compute the offset, the target model runs the motor in the open-loop condition. The model uses a constant (voltage along the stator's d-axis) and a zero (voltage along the stator's q-axis) to run the motor (at a low constant speed) by using a position or ramp generator. When the position or ramp value reaches zero, the corresponding rotor position is the offset value for the Hall sensors.
Estimate PMSM Parameters Using STM32 Processor
Determines the parameters of a permanent magnet synchronous motor (PMSM) using the recommended STM32xx based board. The tool determines these parameters:
Six-Step Commutation of BLDC Motor Using Hall Sensor Feedback for STM32G4xx Based Processors
Control the speed and direction of a three-phase brushless DC (BLDC) motor using the six-step commutation technique in 120-degree conduction mode. The example uses the switching sequence generated by the Six Step Commutation (Motor Control Blockset) block to control the rotor speed and direction by adjusting the three-phase stator voltages.
Hall Sensor Sequence Calibration for STM32G4xx Based Processors
Control a BLDC motor by calculating the Hall sensor sequence with respect to position zero of the rotor in open-loop control. By using this method, you can use six-step commutation to control the motor without the need to label the Hall sensors or derive the switching sequence. Run this example on STM32G4xx Based Processors and obtain the Hall sequence, and use this Hall sequence with the Six Step Commutation (Motor Control Blockset) block to run the motor in closed-loop as explained in the Six-Step Commutation of BLDC Motor Using Hall Sensor Feedback for STM32G4xx Based Processors example. The Hall sequence calibration algorithm drives the motor through a full mechanical revolution and computes the Hall sensor sequence relative to the rotor's position zero in open-loop control.
