Integrated control of position and attitude for terminal guidance of leader-follower anti-ship missiles

An integrated control of position and attitude (ICPA) strategy is proposed by combining the traditional position tracking control and attitude stabilization control together for the cooperative terminal guidance of anti-ship missiles with a leader-follower structure. A cascade type design model, which is convenient for implementing the proposed integrated strategy, is established. The ICPA law is designed using dynamic control, and its stability is proven by Lyapunov method. Followers can accurately track the desired position while ensuring the stability of its own attitude by only obtaining the location information of the leader, but without others as course, speed and attitude. The essence of integrated design philosophy can be summarized that the direct relation between motion and dynamic equations is established by an intermediate state, and then the integrated closed loop algorithm is designed for the obtained cascade design model. Finally, a series of simulations are demonstrated to illustrate the effectiveness of the proposed ICPA strategy and algorithm.
