To solve the finite-time error-tracking problem in mis-sile guidance,this paper presents a unified design approach through error dynamics and free-time convergence theory.The proposed approach is initiated by establishing a desired model for free-time convergent error dynamics,characterized by its independence from initial conditions and guidance parameters,and adjustable convergence time.This foundation facilitates the derivation of specific guidance laws that integrate constraints such as leading angle,impact angle,and impact time.The theo-retical framework of this study elucidates the nuances and syn-ergies between the proposed guidance laws and existing methodologies.Empirical evaluations through simulation com-parisons underscore the enhanced accuracy and adaptability of the proposed laws.
