基于指数加权卡尔曼滤波的组合定姿算法

嵌入式软件系统的测试通常需要对其被控对象或者环境进行仿真,以进行硬件在环的闭环验证,在软件测试中很有必要将被控对象的实时仿真模型与被测系统连接起来进行闭环测试。在总结分析嵌入式测试领域的新需求的基础上,提出了一种基于分布式仿真测试环境的嵌入式软件自动化测试系统。该系统具有较强的测试管理能力,以实时仿真机为核心,以及接口的模块化定制,实现了对系统动态特性的半实物仿真软硬件环境,很好的解决了嵌入式系统内存资源较少,与硬件紧密相关等问题。

Integrated Attitude Determination Algorithm Based on Kalman Filter with Weighted Index

The simulation of controlled object and environment are usually required for embedded software system testing to achieve the purpose of Hardware-In-Loop (HIL) verification. It is necessary to connect both the real time simulation model of controlled object and software to be tested to perform HIL testing. Based on the analysis of latest needs of embedded testing, a system platform in accordance with test automation of embedded software based on Distributed Simulation Testing Environment is proposed in this paper. The testing system implanted with powerful test management function, composed with not only the real-time simulation device as its core but also the modular customization of device interface connected, which actualizes the system level HIL hardware and software simulation environment of dynamic testing of embedded software system and brings out a solution that perfectly handles the defects of embedded system such as deficiency of memory and tightly related with hardware and so on.
