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.
