According to me there is no direct way to simulate drag effect or ground effect in simulink. However, you can still simulate these effects by customizing the model. Here are some steps you could take to incorporate aerodynamic effects into your Simulink quadcopter project:
- Understand the Physics: Ground effect, is the increased lift and decreased drag that a quadcopter experiences when it is close to the ground. Drag is the resistance force caused by the air as the quadcopter moves through it.
- Customize the Model: You can add custom blocks to your Simulink model that represent the aerodynamic effects. For ground effect, you might add a block that calculates additional lift based on the altitude of the drone. For drag, you could implement a block that calculates the drag force opposing the motion of the drone, proportional to the square of its velocity.
- Implement Equations: Implement the aerodynamic equations in MATLAB Function blocks or use Simulink blocks to represent the mathematical relationships
You can take a look at the aerospace blockset which can simulate environemt factors like atmosphere, gravity, wind, etc.
