In a world with limited resources and a growing awareness of the destructive effects greenhouse gasses, the concept of sustainability is becoming more and more prominent in research. Some of the biggest polluters are the aerial shipping and travel industries, for this reason it is vital that they become more sustainable. Therefore a transition from fossil fuels to electric is needed. To completely transition to electric flight seems impossible but nevertheless big companies such as Airbus and start-ups such as Volocopter have started research and development of eVTOL's which are meant as urban air mobility (UAM) vehicles.

This thesis will explore the design of a control system for such an eVTOL. This thesis will be combined with two other theses to create a full theoretical design of an eVTOL. The other two theses will describe the physical design of the eVTOL, the energy storage system and the power train.

The end result of this thesis will be a description of the complete control system for this eVTOL, from what kind of sensors it needs, the mathematical model describing the eVTOL, the design of the control algorithm used, and simulations of the eVTOL in vertical flight.
