摘要:针对系统功能需求分析存在难以准确、充分、结构化识别等问题，本文通过先识别系统所有运行状态，再识别每种运行状态下系统对外部所有输入信号组合的响应输出，综合后获得系统的完整功能需求，显著提高了系统功能需求识别的完整性、准确性。该功能需求识别方法是结构化的方法，易于使用和自动化。结合系统用例、外部参与者、系统外部接口关系、系统外部信号有效范围等方面，提出一种基于自动控制理论的、提升系统功能需求完整性和准确性的分析方法。最后，通过自适应巡航系统实例分析，验证了该方法的有效性。

Abstract:There have been many difficulties in system functional requirements， such as difficult to accurately identify， difficult to fully identify， difficult to identify by structured method， etc. By firstly identifying all operating states of the system， and then successively identifying the response output of the system to all external input signal combinations in each operating state， the complete functional requirements of the system could be obtained after synthesis， which would greatly improve the integrity and accuracy of the identification of system functional requirements. The functional requirements identification method was structured， and was easy to be used and automated. Combined with the system use cases， external actors， external interface relationship， and effective range of external signals， an analysis method based on automatic control theory was proposed to improve the integrity and accuracy of system functional requirements. Finally， an example of adaptive cruise system was given to verify the effectiveness of the proposed method.

Key words:requirement analysis;functional requirement;integrity of requirement;structured requirement analysis;automotive control system
