A new three-dimensional(3D) guidance law is designed using the dynamic surface control method in this paper which is based on the target-missile dynamics in 3D coordinates and the second-order dynamics of the missile autopilot.Certain first-order low-pass filters are introduced into the designing process to avoid the occurrence of high-order derivatives of the line of sight angular rate in the expression of the guidance law,which makes it easy to implement in practical applications.The proposed guidance law...
