A method of designing large envelope flight controllers for high performance aircraft is presented. The approach combines the simple two-degree of freedom architecture and recent advances in parameter-space control design techniques to form a new approach for large envelope flight control design. The procedure enables the designer to explicitly define the desired closed-loop dynamics and ensures that the closed-loop is stable and satisfies weighted frequency response magnitude (Hinfinity ) specifications. The result is a straightforward procedure that enables the design of a robust flight controller that "forces" the closed-loop dynamics to behave like the specified 'desired dynamics' despite disturbances, modeling uncertainties, and variations in aircraft dynamics due to changing flight conditions. The procedure is presented by designing a pitch-rate controller for the F-16 Variable Stability In-Flight Simulator Test Aircraft (VISTA). Finally, the controller is compared to a 7th order and a 10th order linear parameter-varying controller and found to provide better performance and robustness.
