“…In the actual engineering application of path planning for fixed-wing UAV, the real-time characteristics and the small amount of calculation are very important. 19 Therefore, the path planning method based on Dubins path has become an effective and widely used solution, which can realize high-efficient, real-time, and online path planning. 20,21 The Dubins path is a shortest path from the starting point with initial prescribed heading to the final position and heading.…”

“…However, due to the lack of the guidance subsystem, the control lag caused by the large inertia of UAV cannot be solved. Line of sight (LOS) guidance is the most widely used among guidance methods due to its simplicity and ease of implementation and many control strategies combined with LOS has been proposed to meet various practical needs, including unmanned surface vehicle (Jiang et al, 2020; Liu et al, 2015; Rout et al, 2020; Woo et al, 2019) underwater vehicles (Sahu and Subudhi, 2017; Wang et al, 2020) and unmanned aerial vehicle (Chen et al, 2016; Chen et al, 2019; He et al, 2017; Hu et al, 2020; Wang et al, 2019; Zheng and Zou, 2016; Zuo et al, 2019), these LOS-based control strategies can compensate for control lag, but the optimized indicators are generally designed as the shortest settling time and the minimum path deviation, which inevitably leads to overshoot of the following path. This paper therefore introduces a novel guidance and control system based on the IPSO algorithm, the LOS guidance law and the PI controller, which can meet the needs of fast non-overshoot control.…”

“…In the existing literatures, in order to achieve the surrounding attack, the term LOS angle constraint is added to the basic guidance law, so that the designed guidance law can ensure the missile to approach the target with a desired LOS angle. The guidance laws for single missile attacking single target with a LOS angle constraint have been extensively studied [23][24][25]. For the guidance problem of multimissile attack a target with time and LOS angle constraints, some researchers have studied them [26][27][28][29].…”
