Course content

3 sections • 16 lectures • 4h 29m total length

  • DJI Mavic Pro Design Brief8:37

    Model and simulate a DJI mavic pro-style drone in MATLAB and Simulink, derive symbolic dynamics, analyze thrust, drag, gravity and gusts, and design a pid controller for position and attitude.

  • Battery Specifications and Performance4:22

    Analyze the battery specifications and performance of a three-cell LiPo pack, including 11.4 V nominal, 3,800 mAh per cell, 77 A max discharge, and motor limits in Simulink.

  • Empirical Modelling of DC Motors8:20

    Model and simulate a brushless dc motor with kv, back-emf, and voltage-load effects; fit a cubic relation rpm ≈ -2.6931 v^3 + 1400 v to predict speed under load.

  • Empirical Modelling of Propeller's Behaviour and Performance11:47

    We empirically model propeller performance using blade element and momentum theories, using data to relate rpm, thrust, torque, and current for hover.

  • Linear and Rotational Drone Dynamics15:13

    Model a drone's linear and rotational dynamics using a four-rod frame, derive translational motion via Newton's laws and rotational motion via moments of inertia about x, y, and z.

  • Actuation: Moments and Disturbances11:48

    Model thrust and moments from propellers to control a drone, analyze pitch and roll by selective thrust changes, and incorporate drag and disturbances using a simple constant area model.

  • Actuation: Thrust Vectors and Linear Forces18:08

    Explore thrust vectors and linear forces acting on a drone, detailing how roll and pitch alter propeller thrust components and how to project forces into x, y, and z axes.

Requirements

  • Basic understanding of physics (Force, Velocity, Acceleration, etc).
  • High School Diploma mathematics level (Differentiation, etc).
  • Udemy Course Control Systems: From Mathematical Modelling to PID Control (useful but not mandatory).

Description

One of the only comprehensive, detailed and approachable online courses taking you from the mathematical modelling of a quadcopter drone to MATLAB/SIMULINK implementation and PID control design.

Today, drones are everywhere, from ultra high tech military devices to toys for kids going through advanced flying cameras and much more. How do such "apparently" simple machines achieve such precise and impressive flights in varying unstable and unpredictable environmental conditions.

This course gives you the opportunity to learn and do the following:

- Understand and harness the Physics behind a Quadcopter Drone. 
- Establish and approximate the Physics of DC motors and propellers from experimental data. 
- Derive the mathematical equations behind the rotational and linear dynamics of a  drone.
- Implement them in engineering model in MATLAB & SIMULINK using blocks, MATLAB functions, etc.
- Test and fit your model to relevant real life performance and inputs.
- Implement, test and tune PID controllers adapted to your requirements in order to control the output of your system, in this case the altitude, position and attitude of your drone.

I will thoroughly detail and walk you through each of these concepts and techniques and explain down to their fundamental principles, all concepts and subject-specific vocabulary. This course is the ideal beginner, intermediate or advanced learning platform for the mathematics behind engineering systems, the use of MATLAB and SIMULINK in engineering design and PID control. Whatever your background, whether you are a student, an engineer, a sci-fi addict, an amateur roboticist, a drone builder, a computer scientist or a business or sports person, you will master the physics behind an electric car and learn how to implement and control them in SIMULINK by designing powerful PID controllers that bridge the gap between humans and machines!

If you have questions at any point of your progress along the course, do not hesitate to contact me, it will be my pleasure to answer you within 24 hours!

If this sounds like it might interest you, for your personal growth, career or academic endeavours, I strongly encourage you to join! You won't regret it!

Who this course is for:

  • Anyone interested in being able to design control systems for any kind of machine or engineering system.
  • Anyone interested in harnessing the power of MATLAB & Simulink for engineering design.
  • Anyone interested in learning about robotics and PID control.
  • Anyone interested in learning how to model real life engineering systems.
  • Anyone interested in drones, their systems and dynamics of flight.
