In this paper, the gain design process for a nonlinear controller used in a conceptual electrical vertical-take-off-and-landing (eVTOL) vehicle, which has two impellers with one thrust vector nozzle and two wingtip nozzles, is presented. The implemented controller for the eVTOL is based on the incremental nonlinear dynamic inversion (INDI) approach, that ensures the absence of transients throughout the flight envelope by avoiding mode switching. Therefore, a gain design assembly will be presented, which linearizes the plant model without decoupling dynamics firstly and the implemented controller secondly. This allows an investigation in time and frequency domain to compute the gains within the Error Controller (EC) to achieve robustness and a better performance for the entire mission compared to manually tuned controller parameters. By taking the results from the gain design process, nonlinear simulations will be done to show the performance and to proof the behavior of the controller throughout the different phases of flight.
