中文摘要:控制逻辑是机载系统的重要组成之一,对其进行仿真与验证有利于在飞机设计早期发现问题,从而提高系统的安全性。应用Matlab/Stateflow软件平台对民机液压控制逻辑进行了建模,通过控制信号设置和状态转移图的建立仿真实现了液压系统状态监控,泵源附件控制以及指示告警功能。结合液压控制面板的人机交互设计对逻辑模型进行了动态虚拟演示,提高了系统仿真的逼真度,验证了控制逻辑的有效性和准确性。
英文摘要:Control logic is one of the key components of airborne systems. The simulation and verification for the control logic is very helpful to find problems in the early design stage and to improve the safety of the system design. Matlab/Stateflow software platform was used to build the hydraulic control logic model for civil aircraft. By setting up control signals and state transition diagram, the condition monitoring of hydraulic system, automatic control of pump source accessories and corresponding warning functions were realized. A hydraulic control panel was designed and a virtual demonstration was carried out. The fidelity of system simulation was improved and the validity and accuracy for the control logic were verified.
