Abstract

The invention discloses a design method of an automatic pilot for a strapdown seeker. In control structure, a traditional mature three-loop overload tracking mode with pseudo attitude angle is adopted; three dominant poles of the automatic pilot are superposed on a real axis, and the superposed position is far from an imaginary axis on the basis of guaranteeing system stabilization margin and super small reverse overshoot so as to improve rapid response capability. On the basis of existing control system, the rapid response capability of the automatic pilot is lifted as much as possible, and any positive overshoot is avoided at the same time so as to realize overload instruction smooth tracking, reduce unfavorable influence to the strapdown seeker object identification algorithm by the automatic pilot substantially, and lift final hit precision greatly; in addition, the method also has the advantages of simple algorithm and easy engineering realization.

Description

technical field [0001] The invention belongs to the technical field of aircraft control, and more particularly relates to a design method of an autopilot used for a strapdown seeker. Background technique [0002] The design forms of autopilots are different, and corresponding design methods should be adopted according to different application fields, different models and different design requirements. In order to adapt to a wider range of applications, the design method of a highly versatile autopilot needs to consider the versatility of various fields. However, according to the length and short board effect of the barrel, it will inevitably cause waste of resources, increase the cost of model development, and reduce Market Competitiveness. At present, the quick-response strapdown seeker system missile autopilot usually adopts a general-purpose design method. In order to meet the needs of quick response, this method has higher requirements for the rudder system, which not o...
