| 摘 要： | 为了消除线性模型误差的影响,建立了航空发动机性能变化参数非线性估计的模型,提出了一种非线性的航空发动机部件性能变化参数估计的方法。将待估计参数以及模型计算值和实际测量值之间的误差一同并入发动机模型程序进行求解。仿真结果表明,与线性估计方法相比,非线性参数估计的方法具有更高的精度和更简单的系统结构。

| Abstract: | In order to eliminate the effect of the linear model error,the non-linear estimated model of the gas turbine performance change parameter was setup in this paper.Then,a brand-new nonlinear turbine deterioration parameter estimation algorithm was developed with full consideration of the characters of turbine nonlinear simulation program.It made the estimating parameters and the error which is between the calculated and the metrical into one model of gas turbine to program.This new algorithm has a high estimation precision,low computation burden and simple structure. |
