The aim was to develop a system and control model of a VTOL tilt tri-rotor UAV that was a hybrid of a tricopter and an inverted V tail fixed wing aircraft.
- Developed a dynamic non-linear 12DOF model in MATLAB of the fixed wing aircraft
- Modeled the VTOL in both hover and cruise modes and developed a transition controller for the transition flight regime.
- The intermediate control strategy was to use sigmoid functions for different variables and smoothly transition between hover and cruise.
- Used methods such as cascade PID control, decoupling transformation and position control techniques to control the aircraft and tested model in Simulink.
