چکیده

In this paper, the Stability Augmentation System (SAS) is designed to improve the stability while Parallel Evolutionary Optimization based on Lagrangian I1 (PEvolian 11) is successfully applied to satisfy several constraints and to minimize the rising time. A controller to stabilize F-16 aircraft flying with a steady state around the altitude of 25,OOOft is described. The nonlinear pitching motion model of F-16 is linearized in the range of the flight envelope of velocity vs. altitude. Then the statically unstable system is stabilized by applying feedback linearization. As the gain-scheduling method is introduced at various operating points within the flight envelope, the optimized controller is designed all over the envelope. Parallel Evolutionary Optimization based on Lagrangian 11 is used to optimize the proportional and integral gains of the controller, satisfying complex nonlinear Constraints. KeywordsEvolian, constrained problem, Lagrangian, F-16, and parallel evolutionary optimization
