Abstract :
A controller to stabilize F-16 aircraft flying with a steady state around the altitude of 25,000 ft is considered. 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. Evolutionary Optimization based on Lagrangian (Evolian II) is used to optimize the controller gains P and I satisfying complex nonlinear constraints
