A New Impact Time and Angle Control Guidance Law for Stationary and Nonmaneuvering Targets

In this paper, a new dynamic surrounding attack cooperative guidance law against highly maneuvering target based on decoupled model is proposed. First, a new dynamic surrounding guidance strategy is proposed, and virtual targets are introduced to establish the cooperative guidance model for dynamic surrounding attack. Second, a dynamic inverse method is used to decouple the cooperative guidance model, and extended state observers (ESOs) are introduced to estimate the disturbances caused by target maneuver. Then, the impact time and dynamic surrounding guidance (ITDSG) law against highly maneuvering target is designed based on a prescribed-time stable method and the decoupled model. Finally, numerical simulations are performed to illustrate the superiority and effectiveness of the proposed ITDSG.

Cooperative Guidance Law against Highly Maneuvering Target with Dynamic Surrounding Attack

Wang

Fang

et al. 2021

“…In [18], to make full use of the vulnerability of warships, Kang and Kim proposed a linear quadratic differential game guidance law to make the impact angle and time of the missile controllable. A collaborative attack guidance law which can control impact time and angle based on sliding mode control was proposed by Yang et al in [19]. In [20], Harrison proposed a new method to derive the optimal missile guidance law and proposed a threedimensional hybrid guidance law that constrains the impact angle and time.…”

Three-Dimensional Impact Time and Angle Control Guidance Based on MPSP

2019

A new nonlinear guidance law for air-to-ground missile cooperation attacks is proposed in this paper. This guidance law enables missiles with different initial conditions to attack targets simultaneously, and it can also precisely satisfy the terminal impact angle conditions in both flight-path angle and heading angle. The guidance law is devised using the model predictive static programming (MPSP) method, and the control saturation constraint is incorporated in the MPSP algorithm. The first-order-lag acceleration of the missile is taken as the state variable to realize the convergence of the terminal acceleration to zero. Moreover, a collision avoidance strategy for three-dimensional missile cooperative flight is proposed. The simulation results show that the guidance law can make the missiles hit the target accurately at the same time with the ideal impact angles and can realize the control saturation constraints of the missiles. This can increase the attack effects and is significant for collaborative attacks.

“…Zarchan studied a variety of guidance laws for this pursuit-evasion scenario [1]. A new impact time and angle control guidance law against stationary and nonmaneuvering targets was investigated for the missile [2]. A novel extended proportional guidance law was designed to intercept the maneuvering target [3].…”

Evasion-Pursuit Strategy against Defended Aircraft Based on Differential Game Theory

et al. 2019

The active defense scenario in which the attacker evades from the defender and pursues the target is investigated. In this scenario, the target evades from the attacker, and the defender intercepts the attacker by using the optimal strategies. The evasion and the pursuit boundaries are investigated for the attacker when the three players use the one-to-one optimal guidance laws, which are derived based on differential game theory. It is difficult for the attacker to accomplish the task by using the one-to-one optimal guidance law; thus, a new guidance law is derived. Unlike other papers, in this paper, the accelerations of the target and the defender are unknown to the attacker. The new strategy is derived by linearizing the model along the initial line of sight, and it is obtained based on the open-loop solution form as the closed-loop problem is hard to solve. The results of the guidance performance for the derived guidance law are presented by numerical simulations, and it shows that the attacker can evade the defender and intercept the target successfully by using the proposed strategy.
