Abstract
Aiming at the requirements of the terminal impact-angle constraint during the terminal guidance phase of missile,a finite-time convergence terminal guidance law was designed based on the advanced theories of sliding mode control and finite-time control.Considering the specialty that the tracking error on the sliding surface can converge to zero in finite time by using the terminal sliding mode control,the terminal sliding mode surface was selected as the impact angle constraint.The finite-time stabilization-theory was used to analyze the guidance law and prove the finite time convergence feature of the guidance system,and the mathematics expression of the convergence time was given.This proposed guidance-law was compared with another two guidance laws with impact angle constraint.The result shows that the guided missile can hit the target with higher hit-accuracy and less impact-angle error by the proposed guidance.关键词
