The Non-linear Modeling of Generator for AVR Dynamic Performance Test

针对传统调压器动态性能测试方法的不足,提出了构建虚拟平台的概念。在分析调压器动态性能测试需求的基础上,研究了基于模块化建模思想的飞机发电机非线性建模的方法,建立了基于小波神经网络的发电机特性模型,并用所获数据对小波神经网络进行训练,得到了同步发电机突加、突卸负载特性模型,最后对模型进行了验证和误差分析。精度分析的结果表明:所建模型准确有效,用于对配套型号的调压器进行动态性能测试是可行的。

To set up the accurate mathematical model of airplane synchronous generator is the key technology for AVR dynamic performance test.Dealing with the application background of AVR dynamic performance test,a novel idea of setting up the non-linear model of synchronous generator using the modularization method is proposed.A wavelet neutron network model of the impact load and impact unload characteristics of synchronous generator is set up based on WNN.The accuracy of this model is verified using the pre-distributed verification data,and the model for AVR dynamic performance test is feasible.
