    Abstract
  • The existing lateral guidance law for standoff target tracking either converges slowly or has a large steady state error when tracking a maneuvering target. The reference point guidance (RPG) for path following problem was modified as lateral guidance law of unmanned aerial vehicle (UAV) for tracking a maneuvering target. The convergent process of relative distance between and target was modeled by two-dimensional nonlinear differential equations, and then the asymptotic stability of modified RPG was demonstrated. Simulation shows that, the modified RPG has smaller tracking error and integrated time absolute error (ITAE) compared to the methods of Lyapunov vector field guidance (LVFG) and model-based predictive control (MPC), thus the proposed guidance law makes an efficient compensation of the motion of maneuvering target, and has higher steady state accuracy and higher real-time performance.
