Triangle Interception Scenario: A Finite-Time Guidance Approach

الملخص EN

Considering an aircraft threatened by an interceptor, one of the effective penetration strategies is to release a Defender from the aircraft to confront the interceptor.

In this case, the aircraft, the Defender, and the interceptor constitute the three-body guidance relationship, and the cooperation of the aircraft and its Defender to achieve the best tactical effects turns into a concerned problem.

This paper studies the triangle interception guidance problem via the finite-time theory.

The paper presents linear system Input-Output Finite-Time Stabilization (IO-FTS) method.

The sufficient conditions of the linear system, being IO-FTS, under Finite-Time Boundedness (FTB) constraint are proposed, by which the state feedback controllers design method is obtained, via Linear Matrix Inequalities (LMIs).

The triangle interception guidance problems are studied in three different cases, where the proposed methods are applied to the guidance design.

The simulation results illustrate the effectiveness of the proposed methods.
