An open source drone platform offered by Bitcraze actuated minds of various aerial robotic enthusiasts. Over the last few years, research and development on open source drone platform has increased exponentially due to its popularity in wide variety of applications. Simulink extends comprehensive tools to build real time control system. This book provides an extensive information on designing attitude and altitude control algorithms for an open source drone using Simulink. This analysis should help elucidate this approach for future drone enthusiasts build control loops for rapid prototyping on this stabilized platform using Simulink.
