Abstract

Autonomous rendezvous with mobile ground targets is essential in maritime unmanned helicopter missions, such as shipboard recovery, aerial reconnaissance, and target interception. This paper presents an online guidance scheme for rendezvous guidance using the state–dependent Riccati equation (SDRE) technique. First, a typical helicopter-target engagement scenario and the necessary conditions for successful rendezvous are described. After a brief overview of the SDRE technique, three nonlinear quadratic regulator problems for the lateral, vertical, and forward motion each are formulated and solved analytically. The resulting rendezvous guidance laws are then coupled to a robust flight controller in a full-scale helicopter simulation model. The target motion is simulated with a constant ground speed but different lateral maneuvering profiles. Simulations results show that the SDRE guidance laws successfully steer the helicopter for intercepting the target with the required terminal velocity vector.
