The invention belongs to the field of aircraft servo actuation system design, and particularly relates to a distributed redundancy aircraft control surface servo actuation system. The system is mainly composed of a controller and an actuator. A distributed architecture is adopted, and a controller is divided into a first controller and a second controller which jointly control four actuators. The two controllers jointly form a four-redundancy controller architecture, the first controller is a channel A and a channel B, and the second controller is a channel C and a channel D. Corresponding aircraft control surfaces are controlled through the four actuators respectively, the control surface 1, the control surface 2 and the control surface 3 are all of electrical triple redundancy, and the control surface 4 is of electrical quadruple redundancy. Each channel of the two controllers is provided with a communication management module and a servo module. And the communication management module performs information interaction with a flight management system through an external bus. And each communication management module carries out channel cross data link mutual transmission through an internal bus. The safety of the aircraft can be improved while the functional performance of the control system is guaranteed.
本申请属于飞机伺服作动系统设计领域,特别涉及一种分布式多余度飞机舵面伺服作动系统。主要由控制器和作动器组成。采用分布式架构,控制器分为1号和2号两台,共同控制4个作动器。两台控制器共同构成四余度控制器架构,1号控制器为A、B通道,2号控制器为C、D通道。通过4个作动器分别控制对应的飞机舵面,舵面1、舵面2、舵面3均为电气三余度,舵面4为电气四余度。两台控制器的每个通道都具有通讯管理模块和伺服模块。通讯管理模块通过外总线与飞管系统进行信息交互。每个通讯管理模块通过内总线进行通道交叉数据链互传。本申请能够在保证控制系统功能性能的同时提高飞机的安全性。
