Abstract

This paper describes a multi-channel digital control system developed for durability testing of aircraft structures. The system uses parallel processing and inter-processor communication to provide high-speed synchronous MIMO control at update rates to 1000 Hz. Up to 511 separate controllers, each using one Inmos T805 transputer as a processor, are connected in a binary tree to make a single distributed control system. Controllers are located adjacent to actuators, with up to 20 metres between any pair of directly connected controllers. Pneumatic, hydraulic and electromagnetic actuators are supported, with appropriate control laws. A special hardware broadcast link spans the whole network tree and provides critical real-time communications and synchronisation. The application requirements and system design are described. Hardware and software design are discussed, including communications, system management, control software, and safety aspects. Implementation issues are briefly considered. System performance is presented, followed by some general conclusions and observations.<>

并行处理在飞机试验分布式实时控制中的应用

本文介绍了一种用于飞机结构耐久性试验的多通道数字控制系统。该系统采用并行处理和处理器间通信，以1000 Hz的更新速率提供高速同步MIMO控制。多达511个独立的控制器，每个控制器都使用一台Inmos T805变频器作为处理器，以二叉树的形式连接在一起，形成一个单一的分布式控制系统。控制器位于执行器附近，任何一对直接连接的控制器之间的距离可达20米。支持气动、液压和电磁执行器，并具有适当的控制律。一个特殊的硬件广播链路横跨整个网络树，提供关键的实时通信和同步。介绍了应用需求和系统设计。讨论了硬件和软件设计，包括通信、系统管理、控制软件和安全方面。简要讨论了执行问题。介绍了系统的性能，然后给出了一些一般性的结论和观察。
