Research on Optimal Terminal Guidance Law for Anti-ship Missile and Its Simulation

Selecting appropriate terminal guidance law is an important factor for the precise guidance of anti-ship missile.According to the target with uniformly rectilinearly acceleration motion and maneuvering turn,the paper researched an optimal terminal guidance law for anti-ship missile on the basis of the optimal control theory and the dynamics of flight,in this optimal terminal guidance law,both the miss amount and the energy consuming were considered.In the solving of the optimal terminal guidance law,the concept of pseudo control variable was introduced to make the problem less complex.Simulation studies showed that,compared with the traditional approaches,the optimal terminal guidance law proposed in this paper has smaller energy consuming,smaller miss amount and better guidance accuracy,furthermore,its arithmetic is simple.All of those make it has practical values in the engineering applications.
