Synthesis and Analysis of Dynamic Inversion and LPV Tailless Flight Control Law Designs

This paper compares two inner loop flight control law designs for a tailless fighter aircraft model developed from aerodynamic wind-tunnel test data. Dynamic inversion and linear parameter varying control using parameter dependent Lyapunov functions are each used to design control laws for the nonlinear model. The design requirements are stated in terms of flying qualities command responses and robustness and are the same for each method. Detailed low order equivalent systems for flying qualities, structured singular value computations, and batch nonlinear simulations are used to analyze each of the designs in detail.
