摘要
以波音787飞机为例,对多电飞机环控系统组成和原理进行介绍,探讨高速电机驱动的可行性及控制方式。该文采用高速永磁同步电机(Permanent Magnet Synchronous Motor,以下简称PMSM)驱动压气机,同时利用SVPWM(Space Vector Pulse Width Modulation,以下简称SVPWM)技术进行控制,设计了双环控制策略,建立完整的高速电机驱动压气机系统,并利用Matlab/Simulink软件对闭环系统进行建模仿真。仿真结果表明该系统功能完善、稳定性强。
Taking Boeing 787aircraft as an example,this paper introduces the composition and principle of environment control system of more electric aircraft,and discusses the feasibility and control mode of high-speed motor. Choosing high speed permanent magnet synchronous motor to drive the compressor,the control mode is SVPWM (Space Vector Pulse Width Modulation)technology.Double loop control strategy was designed to establish the complete high-speed motor driven compressor system.Then a closed loop system simulation modeling was built based on Matlab/Simulink software.The simulation results show that the system has a perfect function and strong stability.
