Abstract
Cooperative terminal guidance with impact angle constraint is a key technology to achieve a saturation attack and improve combat effectiveness. The present study envisaged cooperative terminal guidance with impact angle constraint for multiple missiles. In this pursuit, initially, the three-dimensional cooperative terminal guidance law with multiple constraints was studied. The impact time cooperative strategy of virtual leader missile and follower missiles was designed by introducing virtual leader missiles. Subsequently, based on the distributed model prediction control combined with the particle swarm optimization algorithm, a cooperative terminal guidance algorithm was designed for multiple missiles with impact angle constraint that met the guidance accuracy. Finally, the effectiveness of the algorithm was verified using simulation experiments.
Highlights
Cooperative guidance is one of the key technologies for multiple missiles to attack and intercept large maneuvering targets with a high accuracy [1,2]
We proposed a three-dimensional cooperative terminal guidance law that met the constraints of impact angle and impact time simultaneously, on the premise of meeting the requirements of miss distance
Based on the model predictive control method, a three-dimensional cooperative terminal guidance law was proposed that simultaneously controlled multiple missiles to perform attacks on the target with the constraints of impact time and impact angle on the premise of meeting the requirements of miss distance
Summary
Cooperative guidance is one of the key technologies for multiple missiles to attack and intercept large maneuvering targets with a high accuracy [1,2]. Li G.Y. et al [5] designed the cooperative guidance law for multiple missiles based on the terminal sliding mode control method and the principle of consistency Designed the cooperative guidance law for multiple missiles to simultaneously intercept high maneuvering targets and designed the cooperative guidance law for multiple missiles based on the terminal sliding mode control method and the principle of consistency to achieve the LOS angle rate of the cooperative missiles converging to zero in a finite time. Based on the model predictive control method, a three-dimensional cooperative terminal guidance law was proposed that simultaneously controlled multiple missiles to perform attacks on the target with the constraints of impact time and impact angle on the premise of meeting the requirements of miss distance.
