Research design of electronic controller simulation verification environment based on real-time operating system

航空发动机作为整个飞机中的核心部件,发生任何故障都会对飞机造成严重的威胁,电子控制器作为发动机系统的中枢指挥,承担着发动机控制、紧急情况响应等关键任务。为保证航发控制器能可靠高效地工作,必须要对其进行全方位、多角度、广范围的迭代验证。硬件在环仿真平台够进行电子控制器全状态功能与性能的仿真模拟,能够有效节约成本、缩短研发周期、降低试车风险,已成为发动机控制器研制过程中的关键技术之一。该文研制了一套仿真验证平台,该平台借助LabView与VeriStand软件,配合各类板卡能实现涡轴发动机控制系统的实时仿真、可对电子控制器进行全功能、性能的仿真验证,为电子控制器的研制提供了有力可靠的支撑。

Aero-engine is the core component of the whole aircraft,and any failure will pose a serious threat to the aircraft.As the central command of the engine system,the electronic controller undertakes the key tasks such as engine control and emergency response.In order to ensure the reliable and efficient operation of the air engine controller,it is necessary to carry out all-round,multi-angle and wide range iteration verification.The hardware in the loop simulation platform can be used to simulate the full state functions and performance of the electronic controller,which can effectively save the cost,shorten the development cycle and reduce the risk of test run.It has become one of the key technologies in the development process of the engine controller.This paper developed a set of simulation verification platform.The platform consists of LabView,VeriStand,and various kinds of board cards,which can realize the real-time simulation of the control system of the turboshaft engine.The electronic controller can carry out full function,performance simulation verification,for the development of the electronic controller provides a strong and reliable support.
