一种相似多通道发动机控制系统控制软件开发

Development of Control Software Which has Application in The Similar Multi-channel Aero Engine Control System

随着全权限数字电子控制系统(FADEC)的发展,要求控制系统中控制软件适应更为复杂的控制场景,使用更为多样的控制方式,以及在系列发动机中,要保持控制规律的一致性,在软件开发维护、调试、验证过程中保证高质、高效。基于这样一种现状,本文介绍了一种发动机控制软件的开发方式,它主要采用了以下方法:1.基于模型设计(MBD)软件设计实现验证方法;2.ARINC659总线的数据通讯;3.非相似多余度控制器硬件平台下的多配置项控制软件相似设计实现;4.分级的测试验证方法。以满足上述控制软件开发要求。

With the development of the FADEC,the control software in the control system is required to adapt to more complex scenarios and use more diverse control methods,it is necessary to maintain the consistency of the control law in series engines,and in the process of software development,debugging,and verification,it ensures high quality and efficiency.Based on such a status quo,this article introduces a certain type of engine control software development method,which mainly uses the following methods are used:1.based on the model design(MBD)software design and implementation verification method;2.ARINC659 data bus communication;3.similar design and implementation of multi-configuration item control software under dissimilar redundancy controller hardware platform;4.multi-level test and verification method.To meet above the control software development requirements.
