The Impact Analysis of Autopilots with Different Structures on Guidance Accuracy when the Guidance Stiffness was Constrained

In order to improve the combat capability of the anti tank missile using the proportional navigation in the near range,the influence of the autopilots with different structures on the guidance accuracy was studied.First,the form of the anti tank missile's guidance system using the proportional navigation was described.Then,the common autopilot was given,and the dynamic performance of different autopilots was compared and analyzed.At last,the corresponding linear proportional navigation guidance system model was analyzed.It was concluded that the guidance precision of corresponding guidance system of damping loop autopilot was the highest under the condition of limited guidance stiffness.
