Problems solved by technology

The timeliness of the non-optimal allocation method is good, but the accuracy is generally poor due to the influence of the actuator constraints; the accuracy of the optimal allocation method is high, but the timeliness is often poor
Considering that the currently used aircraft control allocation method mostly adopts a single allocation method, it is difficult to achieve both timeliness and accuracy of control allocation, so an effective adaptive control allocation method is needed to achieve a trade-off design between timeliness and accuracy

Abstract

The invention relates to a self-adaptive control distribution method for an overdriven aircraft. The method includes the following steps: 1) establishing redundant aircraft system description model with dimensional constraints; 2) generating top control laws through a reference model; and 3) adopting a distribution array and a genetic algorithm to perform self-adaptive hybrid control over a distribution algorithm to perform control distribution. Compared with the prior art, the method has the advantages of being good in timeliness, high in distribution accuracy, high in fault tolerance or thelike.

Description

technical field [0001] The invention relates to the technical field of aircraft control, in particular to an adaptive control distribution method for an overdriven aircraft. Background technique [0002] In order to ensure the reliability of the flight operation of the aircraft, the actuator design of the aircraft generally adopts a redundant configuration design scheme. Such a design scheme directly leads to the dynamics of the aircraft system showing the characteristics of an overdrive system, that is, the corresponding relationship between the desired output and each actuator is no longer clear and unique. In order to obtain actuator control signals that meet actuator constraints and system performance requirements, it is necessary to use a suitable control assignment method to determine the control instructions of each actuator. [0003] For the aircraft control system, the goal of control assignment can be described as: (1) Manipulability: the tracking of the reference...
