Abstract

The invention discloses a pose control distribution method of an aircraft based on multiple execution mechanisms. The method comprises steps of S1, establishing a pose kinetics equation of the aircraft; S2, through a pose transmission matrix, determining a pose angle of the aircraft; S3, establishing a pose kinetics equation of the aircraft; S4, according a control principle, calculating an expected control torque of the aircraft; and S5, by use of a control distribution algorithm, acquiring a state combination of each execution mechanism of the aircraft at the present moment. According to theinvention, the method is suitable for rapid mechanical operaton and high-precision stable mechanical operation task requirements of large-angle poses of the aircraft.

Description

technical field [0001] The invention relates to the field of aircraft intelligent control. More specifically, it relates to a multi-actuator-based aircraft attitude control assignment method. Background technique [0002] The multi-actuator-based aircraft is a multi-purpose and multi-functional new sheet material combination based on intelligent materials, intelligent adaptive nonlinear control distribution technology, and micro-propulsion system. aircraft. The aircraft has a variable skin, which has the advantages of greatly improving the maneuverability of orbit change, achieving the best aerodynamic performance, improving the reusability, and greatly improving the reconfigurability. [0003] This type of aircraft needs to switch quickly between control modes such as attitude maneuvering and high-precision stability. Fast maneuvering buys more time for attacking enemy targets and avoiding enemy attacks, while fast, high-precision stability after maneuvering is to ensure ...
