Abstract :
In this paper we report on combination control strategy with a state-dependent Riccati equation (SDRE) and Taylor series approximations nonlinear predictive control model of a powered parafoil for autonomous agile maneuvering parafoil. NMPC is an optimization based framework for learning a stabilizing control sequence that minimizes a specified cost function. The combinated controller providing an adequate tracking of a prescribed path is designed around a selected flight condition, and make the parafoil operate in a more efficient and reliable manner. It is shown that the designed controller yields satisfactory performances.
