| 摘 要： | 基于卡尔曼滤波器研究旋翼/涡轴发动机的机载自适应模型.采用拟合法建立了状态变量模型,并将发动机性能蜕化参数作为增广的状态变量,设计了卡尔曼滤波器,从而可以根据可测参数的偏离量估计出发动机部件性能蜕化值,最后将部件性能蜕化值用于对机载模型中不可测性能参数的修正,从而使机载模型能适应发动机的非额定工作状况.通过数字仿真表明,建立的机载自适应模型能真实反映发动机的工作状况,并且在全包线范围内该模型都具有比较好的鲁棒性和实时性.

| Abstract: | An adaptive model of rotor/turbo-shaft engine on board was constructed using Kalman filter.The state variable model of rotor/turbo-shaft engine was built through the data fitness method,and a Kalman filter was designed using the deterioration factors as augmented state variables.The Kalman filter can be utilized to predict the component deteriorations from the deviation of measurable parameters,which are used to trim the unmeasurable output parameters of the model on board so that it can adapt the actual en... |
