Road-Map Assisted Standoff Tracking of Moving Ground Vehicle Using Nonlinear Model Predictive Control

You are here

This paper presents a road-map assisted standoff tracking of a ground vehicle using nonlinear model predictive control. In model predictive control, since the prediction of target movement plays an important role on tracking performance, this paper focuses on utilising road-map information to enhance the estimation accuracy. For this, a practical road approximation algorithm is firstly proposed using constant curvature segments, and then nonlinear roadconstrained Kalman filtering is followed. To address nonlinearity from road constraints and provide good estimation performance, both extended Kalman filter and unscented Kalman filter are implemented along with state-vector fusion technique for cooperative UAVs. Lastly, a nonlinear model predictive control standoff tracking guidance is given. To verify the feasibility and benefits of the proposed approach, numerical simulations are performed using realistic car
trajectory data in a city traffic.
