Finite-time attitude cooperative control for roll channels of multiple BTT missiles

This paper considers the problem of finite-time attitude cooperative control of roll channels of multiple bank-to-turn (BTT) Missiles. Based on graph theory, a class of new finite-time controller design methods for attitude cooperative control are proposed. Since BTT missile has the characteristics with time-varying aerodynamic parameters and the requirement of large angle maneuver, etc., it is required the designed attitude controller can offer a fast response rate and strong disturbance rejection performance. To this end, in this paper, based on the technique of continuous finite-time control and the theory of cooperative control of multi-agent systems, a finite-time attitude cooperative control law is designed. Under the designed control law, it is shown that the roll angles of all BTT missiles can achieve states consensus in a finite time. And the final consensus state is the desired roll angle. Simulation results are provided to demonstrate the effectiveness of the method.
