Modeling and Simulation Traffic Alert Collision Avoidance System (TCAS) on Fixed-Wing UAVs

In this study, we propose modeling and simulation of TCAS (Traffic Collision Avoidance System) for unmanned aerial vehicles. First, we explain the main principles of algorithmic performance of the system with respect to its constraints and monitoring criteria. We investigate the nonlinear trajectory equations of the aircraft along the longitudinal axis, while lateral motion is not considered. Using these equations, an inverse dynamic control approach is employed. After that, the simulation results are analyzed and shown in three separate phases of the flight.
