Drone, UAVan autopilot for flight stabilization, and an operator interface to control its trajectory. It consists of models for the aircraft dynamics, the weather, the motor, the actuators and the sensors.

Introduction to Simulink: Quadcopter Simulation and Control

The plant receives commands for the four actuator channels: 1 Throttle, 2 Ailerons, 3 Rudder, and 4 Elevator. In turn, it produces a set of readings as those that a sensor suite would produce on board this type of aircraft. The plant model uses a flat-earth approximation and therefore it will only work for flights which have a range of approximately 20 Km.

The autopilot, based on the ground control station commands and the sensor readings, produces control commands for the control surfaces and also reports telemetry back to the ground station. This block stabilizes the aircraft to keep it in-flight. This represents the console operating the RC Aircraft in flight.

It issues commands sent from the ground to the aircraft waypoints, airspeed, height, etc The block receives telemetry reported by the aircraft such as attitude, sensor readings, and overall aircraft status. This will allow to set the desired behavior of the aircraft while in-flight.

How to make Quadcopter at Home - Make a Drone

This Simulink Project exercises several common workflows in flight control development. Its purpose is to show a recommended approach to a Model-Based Design MBD process to develop a proof of concept Drone flight controller autopilot. Particularly we show the following workflows:. Flight Controller Design Develop a fixed-wing drone autopilot and test its behavior in a reasonably realistic 6DOF aircraft simulation.

Simulate the Flight Controller Under Different Conditions : Rapidly asses the performance of an autopilot under many simulated flight conditions, using local parallel simulations. This model can interact with the Open Source QGroundControl ground station software to control the aircraft while "in flight":. This should produce five plots, the first being an XY plot of a complete mission around 6 waypoints, as shown below:.

To get the full functionality, you will need a Laptop or Desktop computer running one of the operating systems previously mentioned, MATLAB Rb, Simulink, Stateflow, and a supported compiler plus the following products depending on the workflow:. If you are interested in contributing we are definitely interested in hearing from you.

To manage the model and source files, it uses Project Management Simulink. To show the quadcopter in a three-dimensional environment, it uses Simulink 3D Animation. For the collaborative development of a flight simulation application, it provides an implementation of the Flight Simulation application template. Run the following command to create and open a working copy of the project files for this example:.

The x -axis starts at the center of gravity and points in the direction along the nose of the quadcopter. The y -axis starts at the center of gravity and points to the right of the quadcopter. The z -axis starts at the center of gravity and points downward from the quadcopter, following the right-hand rule. We assume that the whole body works as a particle. The file vehicleVars contains the values for the inertia and mass.

Rotor 1 rotates positively with respect to the z -axis. It is located parallel to the xy -plane, degrees from the x -axis. Rotor 2 rotates negatively with respect to the body's z -axis. Rotor 3 has the same rotation direction as rotor 1. Rotor 4 has the same rotation direction as rotor 2.

It is located parallel to the xy -plane, 45 degrees from the x -axis. This example uses the approach defined by Prouty[1] and adapted to a heavy-lift quadcopter by Ponds et al[2]. For control, the quadcopter uses a complementary filter to estimate attitude, and Kalman filters to estimate position and velocity. The example implements:. The controllerVars file contains variables pertinent to the controller.

The estimatorVars file contains variables pertinent to the estimator. The example implements the controller and estimators as model subsystems, enabling several combinations of estimators and controllers to be evaluated for design. The example stores the characteristics for the sensors in the file sensorVars.

To make sure that the trajectory generation tool works properly, the example implements a test in the trajectoryTest file. Toggling between the different visualization variant subsystems.

Note that one of these variants is a FlightGear animation. To use this animation, you must add a FlightGear compatible model of the quadcopter to the project. The software does not include this model.

Provided here is an assortment of materials designed to assist users in modeling and simulation of a quadcopter. These materials are partially the result of a Senior Design project at Drexel University. The team consisted of: D. Hartman, K. Landis, M. Mehrer, S. Moreno, and J. Our faculty advisor was Dr. As this is our first attempt at a public release of our materials, there are undoubtedly errors, omissions, and downright lies contained herein. Expect frequent updates as we find and correct issues.

We do not claim to be experts. All of our materials are provided simply as a service to the multi-rotor community in sincere hope that it will prove useful as a basis for further inquiry. Users are expected to reference our materials against more reliable sources, and use their best judgment or consult professional advice where appropriate, particularly where safety may be a concern.

Quadcopters and RC vehicles are dangerous and are not toys.

Use caution and follow all manufacturer safety instructions. We provide documentation and instructions related to quadcopter dynamic modeing and simulation for control design.Part 1: Setting Up the Control Problem Many quadcopters have sophisticated programmed control systems that allow them to be stable and fly autonomously with little human intervention.

This video introduces the sensors and actuators used in quadcopter control. Part 3: How to Build the Flight Code Discover how to create flight software from the control architecture developed in the last video. Embed this code on the Parrot Minidrone and get the actual hardware to hover. Part 4: How to Build a Model for Simulation This video describes how a good model of the drone and the environment it operates in can be used for simulation and test.

We also walk through a quadcopter model example in Simulink and point out some of the interesting features. Part 5: Tuning the PID Controller This video takes the nonlinear model of the Parrot Minidrone and builds a linearizable model that can be used for tuning the 6 PID controllers in our control architecture.

The software does not include this model. A trajectory generation tool, using the Dubin method, creates a set of navigational waypoints. To create a trajectory with a set of waypoints this method uses a set of poses defined by position, heading, turn curvature, and turn direction.
