[0002] The terminal guidance law is the core technology for controlling guided munitions to achieve long-range precision strikes. It plays a significant role in exerting the huge power of the warhead. With the application of modern control theory in the terminal guidance law, the control performance of the new terminal guidance law is improving day by day. At the same time, its structure is more complex and its parameters increase

[0003] In recent years, my country has vigorously developed high-precision and low-cost guided munitions. At present, the structure and parameters of the terminal guidance law are mainly selected through digital simulation methods. However, this method is only applicable to the classic terminal guidance law with simple structure and few parameters. For new The terminal guidance law is difficult to determine the structure and parameters with high reliability, and it is impossible to carry out the high-cost and long-term live ammunition flight test, which hinders the application of the new terminal guidance law in guided munitions
