I am conducting flight tests using the Simulink Support Package for Parrot Minidrones.

After completing the flight tests, I am analyzing the flight log and encountered the following motor values: [motor values: 301.137787 -294.847717 272.892029 -285.380737].

I am unsure whether these motor values are in the units of PWM, rad/s, or rpm.

Could you please let me know where I can find this information?

Hey,

I understand that you're analyzing flight logs from tests conducted with the Simulink Support Package for Parrot Minidrones and have questions about the units of motor values recorded, such as [301.137787 -294.847717 272.892029 -285.380737].

These values represent motor PWM (Pulse Width Modulation) signals, which typically range from 10 to 500. To estimate motor speed in radians per second (rad/s) from PWM, you can use the formula:

w=sqrt(PWM*13841)

For a deeper analysis, experiment with varying PWM inputs and measure the speeds, then plot speed vs. PWM to understand the relationship better.

Hope this helps!

Regards,
