基于参数辨识的航空无刷交流发电机仿真模型的建立
Establishment of Simulation Model for Aviation Brushless AC Generator Based on Parameter Identification
摘要
Abstract
In the simulation of aviation generators,modeling methods based on voltage and magnetic flux equations have application limitations due to the difficulty in obtaining internal parameters of the generator and the high computational resource consumption.In response to the above issues,this paper proposes a method of establishing an identification simulation model for aviation generators by collecting external data.By collecting the excitation voltage of the exciter and the output voltage of the main generator under different operating conditions of the aviation generator,the transfer function of the aviation generator under different operating conditions is obtained through system identification;By reusing parameter fitting tools,a fitting function of the generator transfer function parameters with changes in operating conditions is obtained,and an aviation generator identification simulation model that does not rely on internal parameters is established.After verification,the identification model can accurately simulate the changes in operating conditions of aviation generators.Compared with the precise simulation model of generators established using voltage and magnetic flux equations,the identification model can significantly improve simulation speed and system simulation efficiency.关键词
