摘要
本文针对多电飞机270V高压直流电源系统带恒功率负载和恒电压负载系统,采用理论分析——李雅普诺夫直接法和建模仿真的方法分析多电飞机电气系统的稳定性。以Buck变换器为例,首先利用李雅普诺夫直接法分析设计了闭环控制的Buck变换器,将它作为电气系统的恒功率负载;然后借鉴基于李雅普诺夫直接法导出的混合势能函数构建多电飞机电气网络的李雅普诺夫能量函数,通过判断系统能量函数的变化判定系统在电源输入电压波动情况下的稳定性,最后采用Matlab/Simulink仿真软件对多电飞机电气系统带不同负载情况进行模拟仿真,验证了直接法在多电飞机电气系统稳定性分析中的正确性,从而为多电飞机电气系统稳定性分析提供了新思路。
This paper mainly focuses the research on the stability analysis of 270 V DC power system with single/double constant volatge load and constant power load on MEA.Lyapunov direct method was used and the results are verified via Matalb/Simulink.Firstly,Lyapunov direct method is made use to design the PWM buck converter,and a vector controlled speed regulation system of permanent magnet synchronous motor was designed,which was taken as constant power load together with PWM Buck converter to the electrical power system of MEA.Secondly,the Lyapunov energy function was built for the aircraft power network on the base of Brayton-moser theorem.The stability of the power system was analyzed by the variation of that energy function.Finally,when different load operating conditions were taken into account,the Matlab / Simulink simulation software was used to verify the theoretic analysis.The results show that a new way has been provided to analyse the stability of the electrical power system with complex loads on MEA.
