Abstract

Aiming at the problem that parasitic loop caused by radome error affects the stability of guidance loop, this study establishes a three-dimensional nonlinear model of guidance loop with the radome parasitic loop and proposes a stability analysis method of the radome parasitic loop based on Lur’e system model. Taking the parasitic loop caused by nonlinear radome error slope as a nonlinear part of the Lur’e system, this paper analyzes the Lyapunov stability by the passivity theorems to calculate a sector area condition that the nonlinear radome error slope needs to meet. Finally, a numerical example based on nonlinear model of the guidance loop is given to verify the correctness of the method proposed in this paper.
