this example enables you to use any custom motor-control hardware (hardware not used in the motor control blockset™ examples) to run a three-phase permanent magnet synchronous motor (pmsm) using field-oriented control (foc). using the algorithm export workflows, which involve generating code for the control algorithm by using simulink® and embedded coder® and then integrating it with either manually written or externally generated hardware driver code. this example explains the algorithm export workflows along with the intermediate steps.

the example uses the following hardware as a reference, but you can use any motor-control hardware:

you can use this example to customize the control algorithm and integrate it with the drivers for your motor-control hardware. in this example, we use the software to configure and generate code for the hardware drivers. this example supports any three-phase pmsm.

implementing the foc algorithm needs real-time rotor position feedback. this example uses a quadrature encoder sensor to measure the rotor position. for details about foc, see .

the example includes three workflows.

1. open-loop control and adc offset calibration — this workflow uses an algorithm that runs a pmsm using open-loop control (also known as scalar control or volts/hz control). you can use this workflow to check the integrity of the hardware connections and calculate the adc offsets for the current sensors available on the hardware.

2. quadrature encoder offset calibration — this workflow uses an algorithm that calculates the offset between the d-axis of the rotor and the index pulse position as detected by the quadrature encoder sensor. the control algorithm (available in the field-oriented control workflow) needs this offset to accurately compute the rotor position, which is necessary to implement foc.

3. field-oriented control — this workflow uses an algorithm that runs a pmsm using closed-loop field-oriented control (foc). the workflow uses the adc and quadrature sensor offsets as inputs.

each workflow includes these steps to prepare, deploy, and run the algorithm on your hardware:

1. generate code for the control algorithm using embedded coder®

2. obtain c code for hardware drivers

3. integrate control algorithm code with the driver code

4. deploy the integrated code to hardware

5. control the motor using a host simulink® model.
