UAV Algorithm Design

Guidance models, MAVLink communication, waypoint following

Unmanned aerial vehicles (UAVs) can be modeled and controlled using UAV Library for Robotics System Toolbox™ functions, objects, and blocks. You can simulate a reduced-order guidance model for fixed-wing and multirotor UAVs that approximates a closed-loop autopilot controller with a kinematic model. Generate control commands, UAV states, and environmental inputs using the given functions. A waypoint follower is also provided to execute flight missions based on given waypoints. Communicate with UAVs using the MAVLink communication protocol to send and receive messages.

Note

Using UAV Algorithms requires you to install the UAV Library for Robotics System Toolbox. To install add-ons, use roboticsAddons and select the desired add-on.
