摘　　要：以反映部件健康状态的变几何涡轴发动机部件级数学模型为基础,利用线性化方法建立了反映航空发动机健康状态的线性状态空间数学模型;利用Kalman滤波器原理,构建了涡轴发动机健康状态跟踪滤波器。对线性状态空间模型和健康状态跟踪滤波器进行了仿真,结果表明:线性状态数学模型准确、实时;健康状态跟踪滤波器可准确地估计出涡轴发动机健康状态的变化。Based on variable geometry turboshaft engine component level mathematical model reflecting component health,a linear state space mathematical model reflecting aeroengine health state was built using linear method.The health state tracking filter of the turboshaft engine was built by Kalman filter theory to simulate the linear state space model and health state tracking filter.The simulation results show that the linear model works well with high fidelity and real-time,the tracking filter can identify the health status of turboshaft engine accurately.
