A terminal guidance law based on zero-effort miss distance was designed with sliding mode approach for attacking a manuvering target.First of all, according to the motion equations of the missile and target, a system model was established.Secondly, the zero-effort miss distance was selected as a switching surface of sliding mode, and the terminal guidance law of the pitch channel was deduced using exponential reaching law and the fuzzy control method.Finally, trajectory simulation was carried out for a snakelike maneuvering target, which verifyed the feasibility and effectiveness of the designed guidance law.In addition, the simulation results also show that in solving such problems as fluttering with sliding mode guidance law, the method with fuzzy control has better robustness and is more effective than the method using saturation function instead of signum function.
