一种高性能航空直流起动发电机控制器设计

Design of a High Performance Aviation DC Staring Engine Controller

针对传统模拟式发电机控制器性能提升与轻量化设计需求,提出一种模块化、数字式起动发电一体化控制器系统架构,规划了基于DSP与FPGA的通用CPM模块,完成了PSM模块、E3M模块与RVM模块的硬件设计,并针对软件的可移植性开展了分层解耦架构设计。测试结果表明:设计的GCU产品,大幅提升了产品的测试性、维护性,降低了环境变化对发电机电压控制品质的影响,减小了产品的体积重量,为飞机电源系统功能与性能提升提供了有效的解决方案。

Aiming at the performance improvement and lightweight design requirements of traditional analog generator controllers,a modular and digital starting engine generation integrated controller system architecture is proposed.The planned general purpose CPM module based on DSP and FPGA completes the PSM module.The hardware design of the E3M module,the RVM module,and the layered decoupling architecture design for software portability.The test results show that the GCU products in this paper greatly improve the testability and maintainability of the products,reduce the impact of environmental changes on the voltage control quality of the generators,reduce the volume and weight of the products,and provide an effective solution of the functions and performance improvements of the aircraft power system.
