Field-Oriented Control of BLDC with Encoder Using Infineon AURIX Microcontrollers

Implement the field-oriented control (FOC) technique to control the speed of a three-phase brushless DC (BLDC) motor. The FOC algorithm requires rotor position feedback, which is obtained by using an encoder sensor. For more details about FOC, see Field-Oriented Control (FOC) (Motor Control Blockset).

Analyze Sensorless Observers for Field-Oriented Control Using Multiple Cores of Infineon AURIX

Use Embedded Coder® Support Package for Infineon® AURIX™ Microcontrollers for sensorless field-oriented control using multiple cores of an Infineon AURIX microcontroller board. This example uses a top-level model and two referenced models. You use the TriCore0 referenced model to implement a sensor-based field-oriented control (FOC) technique to control the speed of a three-phase brushless DC (BLDC) motor. You use the TriCore1 referenced model to implement and analyze different sensorless algorithms, such as the algorithms implemented in the Flux Observer (Motor Control Blockset), Sliding Mode Observer (Motor Control Blockset), and Extended EMF Observer (Motor Control Blockset) blocks.

Ports

Input

msg — SoC Blockset simulation message

scalar

This port receives the SoC Blockset™ message from the interface blocks and the Digital Port Read block converts the msg into data to be emitted at the output port during simulation.

Dependencies

To view this port, select the Enable simulation port parameter and set the port type as SoC Data (Message based).

sig — Simulink based simulation signal

scalar | vector

The simulation-only signal input port acts as pass-through with the output of the Digital Port Read block during simulation.

Dependencies

To view this port, select the Enable simulation port parameter and set the port type as Signal.

Output

pin(s) — GPIO pin status

scalar | vector

The port outputs the status of the digital pin you select in the Port number and Pin number parameter from Digital Port Read Peripheral Configuration.

The port outputs the status as a logical scalar if the pin number is 1 or as a logical vector if it is greater than 1.

Data Types: Boolean

Parameters

Number of pins — Number of pins you want to configure

1 (default) | 2 | 3 | ...

Select the number of pins (1 to 16) whose output you want to configure in the block.

Sample time — Frequency at which block reads input pin values

-1 (default) | scalar | vector

Specify in seconds how often the block should read the pin value.

When you specify this parameter as -1, Simulink^® determines the best sample time for the block based on the block context within the model.

Enable simulation port — Enable peripheral simulation ports in the block

off (default) | on

Select this parameter to enable peripheral simulation capability.

Port Type — Specify the type of peripheral simulation port

SoC Data (Message based) (default) | Signal

Select this parameter to configure either the SoC compatible or the Simulink signal based simulation ports to enable peripheral simulation capability.

Dependencies

To view this parameter, select the Enable simulation port parameter.
