    摘要:

    针对飞控系统进行动态特性和故障特性分析;基于模型故障检测方法研究的需要,开展了飞控系统及其故障的非线性建模与仿真平台开发的研究。定义了典型的飞控系统结构,建立了舵机、力综合臂、传感器和作动器的数学模型,进行了飞控系统各部分典型故障模式分析,建立了飞控系统各部分故障的数学模型。以MATLAB/Simulink为工具开发了飞控系统及其故障的仿真平台,可方便地完成系统及其故障的动态特性仿真。仿真试验验证了飞控系统及其故障数学模型和仿真试验平台的合理性。

    Abstract:

    Considering the requirements of dynamic character analysis, fault character analysis and model-based fault detection of flight control system,nonlinear model and simulation platform of flight control system and its fault ware studied. One of classical flight control system structure was defined, and the models of rudder, force integration arm, sensor, actuator ware built. The typical failure modes of flight control system different part ware analyze, based on that, the fault models of flight control system different part ware built. From this, simulation platform of flight control system and its fault was development based on MATLAB/Simulink, which can simulate dynamic character of system and its fault easily. Based on simulation testing, the rationality of model and simulation platform of flight control system and its fault are verified.
