摘要
研究利用AMESim和MATLAB Simulink联合仿真技术,建立了高精度非线性电静液(EHA)作动的二元机翼阵风减缓系统仿真模型,基于该模型研究了EHA舵偏传感器功能丧失和异常情况下对阵风减缓系统的影响,仿真结果表明:在这些故障情况下,系统在一定失效范围内仍有减缓效果,但会产生极限环振荡;超出该范围,系统的振荡幅值以及振荡频率都将改变,系统产生非周期性不规则振荡或周期性不规则振荡。
Based on the AMESim and MATLAB Simulink simulations,a simulation model of the binary wing wind alleviation system with high precision nonlinear electro-hydrostatic(EHA)action is established.Based on this model,the EHA rudder deflection sensor is lost and abnormal The simulation results show that under the condition of these faults,the system still has the effect of slowing down in a certain failure range,but it will produce the limit cycle oscillation.Beyond this range,the oscillation amplitude and oscillation frequency of the system will be change,the system produces aperiodic irregular oscillations or periodic irregular oscillations.
