Kavramsal çok pervaneli bir e-VTOL hava aracı için blended-ınverse kullanarak kontrol dağıtımı

In this thesis, the control allocation problem in a flight control system design for a multi-rotor eVTOL (electric Vertical Takeoff and Landing) aircraft is proposed. The vehicle consists of 20 identical rotors that are used as flight control actuators. The dynamic system is a MIMO (Multi Input Multi Output) system with more inputs than outputs, i.e. there are many solutions of the control problem. The objective is to find an efficient and redundant control solution that provides sufficient flight performance, handling quality, and power consumption. Developed control system algorithms are applied to a simulation model of the conceptual aircraft consisting of advanced and nonlinear dynamic components. By using this model, simulation based flight tests are conducted and the results are presented and evaluated. Also, redundancy of the control system is considered for flight safety. Therefore, various simulator based rotor failure scenarios are tested on the aircraft and the proposed method is also evaluated from a redundancy point of view. It is shown that robust and efficient control redistribution can be achieved using the proposed solution under challenging failure conditions.
