基于xPC的飞行控制系统半实物仿真设计

摘要

利用Matlab的xPC目标工具在仿真回路中引入飞控计算机、传感器等实物部件,设计了某型飞机飞行控制系统的半实物仿真系统.根据飞行控制系统的原理特点设计了数据采集卡与信号转换处理电路,并在VC 6.0环境下对系统软件进行了编制.仿真结果表明:该半实物仿真系统具有较高的仿真置信度和可靠度.%With the introduction of flight control computers, sensors and other physical components to the simulation loop, semi-physical simulation system of an type of aircraft is designed by xPC target tool of Matlab.Data acquisition card and signal transition and processing circuit are designed according to the principles and characteristics of flight control system. System software is programmed under VC 6.0. Simulation result shows that the semi-physical simulation system has high confidence level.
