PX4 SITL with simulink based plant model, system not found

9 views (last 30 days)
I'm performing the SITL using the PX4 toolbox on Simulink on Windows 11. I'm following the px4demo( ) provided my Mathworks to perform the SITL on PX4 host target on the Simulink plant(so using simulink as simulator,no jmavsim). When I open the simulink plant "Quad_Plant_top" (MATLAB\Examples\R2023b\px4\MonitorTunePX4HostTargetFlightPlantModelExample7\Px4DemoHostTargetWithSimulinkPlant/models/Quad_Plant_top), I have a problem on the Simulink block (Matlab system) as shown in the picture. How can I solve this problem? Thank you

Thanks for reporting this issue. This a bug and we are working to push the fix out. I am attaching 3 MATLAB scripts in this answer. To workaround the issue
  1. Open the Example in MATLAB
  2. Navigate inside the "Px4DemoHostTargetWithSimulinkPlant" folder.
  3. Navigate to the "scripts" folder.
  4. Copy the attached MATLAB scripts in the "scripts" folder.
  5. Open the "Quad_Plant_top" model and you should see the issue resolved.
