N2 - A new mechanism of missile agile turn and its control method are proposed for problem of missile attacking rear targets in this paper. Firstly, a new agile turn mechanism for missiles is defined; Secondly, the dynamic model for missiles with blended lateral thrusters and aerodynamic control systems including a deceleration parachute is established; Next, aiming at the singularity problem of traditional terminal sliding surface, a finite time convergent agile turn non-singular sliding mode controller is designed by using a segmented sliding surface; Then, the extended state observer is designed to eliminate control chattering, and the system stability is proven based on Lyapunov stability theory; Finally, the effectiveness of the proposed new mechanism of agile turn and the control method is proved through simulation and analysis. Compared with the traditional agile turn mechanism, the method proposed in this paper can significantly reduce the turning radius of the missile, while achieving greater terminal speed, the system states converge more quickly, the singularity problem and chattering are avoided.
