A fuzzy guidance law design with terminal-angle constraint

In this paper, a kind of reference trajectory of line-of-sight angle based on the optimal control theory is given, which can make the missile hit the ground fixed target accurately and satisfy the demand for terminal-angle constraint. Then, the corresponding fuzzy control law is designed to achieve the tracking of the reference trajectory of line-of-sight angle. Simulation results show that the proposed fuzzy guidance law has high control precision and can meet the demand for terminal-angle constraint.
