Three-Dimensional Interception Guidance Law for Cooperative Aircraft in Finite Time Based on Non-Singular Sliding Mode Control

This paper proposed a 3D cooperative guidance law for aircrafts in formation based on finite-time convergence and non-singular sliding mode control method. Referring to the distributed “Lead-Follower” structure and set relative adjustment time-to-intercept as distributed signal of communication in formation, the designed guidance law could converge in a limited time and dealing with the situation, which the angles of sight between intercepting aircrafts and target change rapidly and turn to singular. Numerical simulation result proves that the cooperative guidance law designed in this paper is effective and reliable.
