Özet

This paper addresses the design of a nonlinear tracking controller for an unmanned aircraft. A State Dependent Riccati Equation (SDRE) method is utilized in a parallel-loop controller structure. We consider a classical approach of separating dynamics of a fixed- wing aircraft into longitudinal and lateral. SDRE controllers are designed for each of these control channels. The coupling effects, and nonlinearities are reected in the extended parametrization models of the channels. A nonlinear simulation model of an aircraft is used to validate the performance of the proposed control algorithm. Simulation results show the effectiveness of the algorithm for a coordinated turn maneuver.
