Title: Advanced Two-Dimensional Proportional-Derivative Command to Line-of-Sight Guidance Laws Keywords: command to line-of-sight (CLOS) guidance, anti-tank guided m Abstract: There is usually seen a trajectory not lying on a straight line but a spiral type trajectory in the plane perpendicular to the line-of-sight (LOS) called also the picture plane during the transient process of putting a command to line-of-sight (CLOS) anti-tank guided missile (ATGM) from the initial deviations in both vertical and horizontal planes onto the LOS implementing the CLOS guidance even though the target is non-maneuvering. This occurrence worsens the performance indicators of the ATGM system. In order to modernize the synthesis of the classical spatial closed loop guidance and control systems with new guidance laws which overcome the classical immutable but unfavorable characteristics a set of several new nonlinear guidance laws has been developed. The new guidance laws fight effectively the spiraling trajectories in the picture plane due to the phase coupling between the horizontal and vertical channels and/or existence of non-proportional to each other initial conditions.
