I am unable to interface Arduno and simulink with Rhino BLDC motor driver setup to control speed.

The speed control of BLDC motor is what I am trying to do. But before that the open loop speed control on BLDC motor using PWM generation is what I want to do with Arduino Mega 2560.

I require certain documentation regarding interfacing of Arduino Mega 2560 to simulink model for speed control of BLDC motor.

Hi Prateek,

For open-loop speed control of a BLDC motor using an Arduino Mega 2560 in Simulink, you can follow the below steps:

• Ensure you have installed the “Simulink Support Package for Arduino Hardware”. You can find it by navigating to Add-Ons > Get Hardware Support Packages in MATLAB/Simulink and searching for the Arduino package.
• Use the “PWM Output” block from the Simulink Support Package for Arduino Hardware to generate the PWM signal for speed control.
• Configure the “PWM” block with the appropriate pin number connected to the motor driver input.
• Set the PWM frequency and duty cycle according to the motor requirements.
• Go to “Model Settings (Ctrl+E)” and set the solver type to “Fixed-step”. Choose a fixed-step size that matches your control requirements.
• In the Hardware Implementation pane, select “Arduino Mega 2560” as the target hardware.
• Click on the “Deploy to Hardware” button in Simulink to upload the model to the Arduino Mega 2560. This will compile the model and upload the generated code to the Arduino.
