An impact angle control guidance law is proposed for stationary target interception considering missile's field-of-view limit and speed changes. The proposed impact angle control guidance law is structured as a biased proportional navigation with a time-varying bias. The proposed guidance law does not involve any switching logic for maintaining lock-on; hence, the guidance command is continuous during the entire engagement. Unlike the most existing studies, the proposed method guarantees that the impact angle error converges to zero before interception without the constant-speed assumption. To realize these desirable properties, the positive invariance of the bounded look angle interval and the change of independent variable are utilized. Numerical simulations are conducted to demonstrate the performance of the proposed guidance law.

“…Table 1 summarizes the root-mean-square results of the Monte Carlo simulations except the approach. 21 This table shows that the both indirect guidance methods 15,16 meet the impact angle constraints within the impact angle error [γM-γM f]rms<7.8∘. To clarify the performance comparison, the Monte Carlo simulation results are shown in Figure 8.…”

“…Meanwhile, the SMC-based guidance law 21 is designed as aM=F(λ,θM)VMsgn(S). In this case, when the magnitude of F(λ,θM) is large, the guidance command is amplified even for small noise components on the sliding surface, and it would be saturated eventually.…”

“…Figure 5(a) presents a flight trajectory with a different shape than that shown in Figure 3 Performance comparison study with other guidance laws. In this subsection, the performance of the proposed guidance law is compared to other guidance approach represented in Erer and Merttopcuoglu 15 and Kim et al 16,21 The first two guidance laws are the indirect guidance approach that does not use the impact angle error directly in order to control the impact angle, and the third is the direct guidance method based on the SMC. In the presence of noise, a Monte Carlo simulation of 200 sample runs was performed for each case with or without FOV limits.…”

“…Motivated by these observations, recently, the SMC-based guidance law applicable to a passive homing missile is proposed for the impact angle control considering the seeker’s FOV constraints. In Kim et al., 21 a magnitude-limited sigmoid function in a switching surface is introduced to confine the look angle not to exceed the FOV limit. The derived guidance law does not involve the range or time-to-go information and does not even require line-of-sight rate information.…”

A guidance problem for impact angle control applicable to a missile equipped with a passive seeker is investigated. The proposed guidance law based on the sliding mode control consists of the proportional navigation guidance term with a varying navigation constant and the additional biased term which is a function of the novel sliding surface. The guidance law directly uses the impact angle error but does not require any range information to be estimated by the additional filter loop of the passive seeker. The asymmetric limit of the passive seeker’s field-of-view is also taken into account, which is not violated by introducing a continuous switching function. The finite time convergence properties are analyzed, and nonlinear simulations are performed to investigate the effectiveness of the proposed guidance law.

This article proposes a multimissile cooperative guidance law for simultaneous attacks with impact angle constraints based on an event-triggered strategy.The guidance law has two parts. One part is derived from optimal control to satisfy impact angle constraints, and the other is a cooperative term to perform simultaneous attacks. An event-triggered strategy is introduced to reduce communication frequency and save energy. The consensus is proved by the Lyapunov theory. Efficacy of the proposed guidance law is verified by numerical simulations.
