Parameter Robust Game Theoretic Synthesis for the F-18 HARV

摘要

A parameter-robust game theoretic compensator has been designed for the F-18 High Angle-of-attack Research Vehicle (HARV). Modelling uncertainties due to parameter variations in the aircraft dynamics over varying flight conditions are included in the design process by using a internal feedback loop (IFL) decomposition and incorporating the resulting state space into a disturbance attenuation problem. The compensator is designed to track pilot inputs in angle-of-attack, sideslip, and stability-axis roll rate through stick and rudder pedal commands. Zero steady state error in the presence of step inputs is achieved by using a system of error coordinates which also allows for thrust vector commands to fade to zero in steady state. Linear and nonlinear simulation results are presented.
