Abstract

The invention discloses a multi-airplane formation flight control method comprising the following steps: in step S1, according to initial formation design, an initial formation matrix is constructed; in a step S2, in practical flying processes, a practical formation matrix is constructed; in step S3, a strategy set is determined according to airplane performance boundaries; in step S4, an error matrix is calculated, and an error matrix determinant is associated with a formation situation value; in step S3, according to the strategy set determined in step S3, each strategy is gone over, and a strategy corresponding to a maximum formation situation value is chosen and executed; in step S6, an instruction corresponding to the maximum situation value is transmitted to an automatic flight control system which can control a flying state of an airplane, and therefore target formation control can be fulfilled; in step S7, if disturbance occurs in a target formation and the formation situation value can reach a maximum state, then procedures from step S1 to step S6 are repeated. The beneficial effects of the multi-airplane formation flight control system are that when a problem of fixed formation flight control is solved, a problem of group formation flight control is also addressed, and a multi-airplane task execution success rate is improved.

Description

technical field [0001] The invention relates to the technical field of flight control, in particular to a multi-aircraft formation flight control method. Background technique [0002] The task of formation flight control is to control multiple aircraft to fly in the air according to a predetermined formation, and provide technical support for manned aircraft flight performances and unmanned aerial vehicle formation flight. [0003] With the increasing development of UAV technology, the demand for reconnaissance and strike combat missions based on multi-aircraft formations is becoming more and more obvious. A multi-aircraft cluster flight control method suitable for reconnaissance is required, and at the same time taking into account the need for concealment. The formation flight control method of multi-aircraft flying in tight formation to reduce the detection of enemy radar has become a major difficulty in research. Due to the limited shape, it is impossible to realize the...
