I want to run a flight controller implemented by Simulink with PIXHAWK (I want to turn the motor)

Hello

I'm sorry in poor English.

I am planning to fly drone by connecting MATLAB / Simulink and PIXHAWK.

MATLAB version is R2017b

PIXHAWK uses PIXHAWK2.

Using the manual (Pixhawk Pilot Support Package (PSP) User Guide), it is possible to build the environment of Windows 10 and Ubuntu, “build” and “UPLOAD” of the sample model (px4demo_attitude_system_multi_task.slx).

In order to operate the Simulink model, I placed the file (rc.txt) in the etc folder of the SD card according to the manual. The file is pasted rc.tct which exists in C \ px4_firmware _ *** of PC.

And I turned on the power, but the motor did not rotate.

We built a sample model (px4demo_rgbled.slx) that lights the LED to investigate the cause, and when it was uploaded, we could see that the LED turned on at the intended timing and the color changed.

According to my guess, I think that an instruction to turn the motor is necessary in rc.txt.

Please tell me how to change rc.txt.

If my guess is wrong, please tell me how the motor turns. I write the rc.txt that I use below.

Dear All,

Greetings!

We use HexSoon Edu 450 Quadrotor with Pixhawk autopilot. We collected flight data for parameter estimation and modeling. Controller is also designed for the model parameters and ready in m-file as well as simulink. We are facing problem in dumping the controller with reference to the Pixhawk autopilot.

Need any advice for solving this issue. We also installed px4_fmu-v3_default firmware from MATLAB and validated the firmware too.

Need suggestions to embed the control algorithms into the Pixhawk autopilot.

THanks in advance

Dr Arasu,

Are you still facing any issue? I recommend creating a separate question if you still have any issue?
