Design of 3-D discrete sliding mode variable structure guidance law for air missile

Based on kinematics relationship model of missile and target in three-dimensional space, this assignment will extend 2-D plane to realistic 3-D space. Firstly, it will deduce 3-D Guidance Law Model between air missile and maneuvering target. Then this assignment will design suitable discrete sliding mode variable structure guidance law through the robustness characteristic controlled by sliding mode. The guidance features will be subsequently analyzed. Finally, the result will confirm the feasibility of the designed guidance law through the mathematical simulation.
