Coupling Effects and Decoupling for Supersonic Flight Vehicle
Author:
Abstract: In this paper, a nonlinear decoupling technique is used to design an aerodynamic coupled missile flight control system. The decoupling are get from multiplications of two measurable accelerations and three controllable output commands of the autopilot. They give exact sign and magnitude of aerodynamic coupling directly in missile manoeuvre. From frequency responses of coupling terms, decoupling terms and inner open-loop Bode diagram of the rolling channel, it will be seen that the decoupling and robustness for aerodynamic couplings can be obtained simultaneously. The time responses give same conclusions.
