Design of Three-Dimensional Path Following Guidance Logic

Abstract EN

This paper presents a three-dimensional path following guidance logic.

The proposed guidance logic is composed of the guidance law and the motion strategy of virtual target along the desired path.

The guidance law makes a vehicle purse the virtual target, and the motion strategy explicitly specifies the motion of virtual target by introducing the concept of the projection point and the tangentially receding distance.

The proposed logic is simple and efficient and yet provides precise path following.

Numerical simulations are performed to demonstrate the effectiveness of the proposed guidance logic.
