摘　　要：针对某型号飞机进行了飞行控制系统的建模与仿真,包括控制律建模,飞行方式控制面板的软件实现以及两者的集成。其中,控制律模块包括电传控制模块、自动驾驶仪模块、自动油门模块、偏航阻尼器和飞行指引模块。该飞行控制系统中控制律的建模均在MATLAB/SIMULINK开发环境中实现,飞行方式控制面板在Visual C++开发环境中实现,两者通过SIMULINK/RTW代码生成工具及其接口函数的调用进行集成。这种方式在开发软件的选择上扬长避短,有利于模型的结构化建模且缩短了控制系统软件的开发周期,并且对飞行控制系统自测试功能的开发提供了有力的支持。仿真实验证实,所采用的方案简单、有效,且建模的精度满足要求。The modeling and simulation of flight control system for a certain aircraft model were conducted,including modeling of control laws,realization of Flight Mode Control Panel software and their integration.The control law module includes fly-by-wire control module,autopilot module,auto throttle module,yaw damper and flight director module.The control laws of the flight control system were developed using MATLAB/SIMULINK,while the Flight Mode Control Panel was achieved using Visual C++,and they are integrated with SIMULINK/RTW code generating tool and the invoking of interface functions.This way of selecting developing software adopts their strengths and avoids their shortcomings.It is not only conducive to structured modeling and shortens the development cycle,but also provides powerful support for developing self-test function of the flight control node.Simulation experiments confirm that the method is simple,effective,and meets the requirements in modeling accuracy.
