多舵面飞机电力作动系统协调控制策略研究

Research on coordinated control strategy of electromechanical actuation system for multiple control surfaces aircraft

随着大型飞机舵面结构布局的变化,传统的集中式结构飞控系统难以满足舵面协调过程中准确性的要求。为此引入多智能体的概念,将单个舵面等效为一个智能体,构建分布式电力作动系统的多智能体系统结构。采用联盟式体系结构,分别对联盟内部分体式舵面智能体的同步联动控制、不同联盟间舵面协调偏转控制进行控制策略的设计,并建立仿真模型。仿真结果表明,舵面能够准确地收敛到给定的舵面协调偏转状态,并且该策略能有效抑制舵面负载干扰引起的协调偏转率波动,解决了传统集中式飞控系统多舵面协调控制准确性不好的问题。

With the changes in the structure of the layout of large aircraft control surfaces,the traditional centralized structure of the flight control system can not meet accuracy requirements in the rudder coordination process. To solve this problem,the concept of multi-agent was introduced and a single rudder was equivalent to an intelligent agent to build a distributed multi-agent system structure of electromagnetic actuation system. The coordinated control strategy of split type actuator synchronous linkage control and the control surface coordinated control respectively were designed with federated architecture,and the simulation model was established. Simulation results show that the rudder can accurately converge to a given coordinate rudder deflection state,and the strategy effectively suppress interference caused by fluctuations in load rudder deflection rate coordination,solved the problem of poor coordinated control surface accuracy of traditional flight control system.
