基于双 DSP 平台的飞/推综合控制优化计算机设计
ABSTRACT
The overall performance of airplane and aero-engine can be optimized by
applying the technology of Integrated Flight / Propulsion Control (IFPC) in a
puter, where the modified control instructions is calculated for the
engine controller based on the informations from the airplane and the aero-engine.
Through appending the munications element (ACE)
TL16C554 and plex Programmable Logic Device (CPLD), the first
edition puter which processor is TMS320VC33 DSP is improved
greatly. And the result of Hardware-in-Loop simulation indicates that serial
communication can satisfy the puter requirements.
In order to increase operation speed and integrate degree of optimization
computer, the two-core hardware frame in which TMS320C6713 and TMS320F2812
are adopted is presented in this paper. At the same time Detailed circuit design and
particular principle machine design are given too. Then researched the software
design process based on puter of double DSP and maded a series of
experiments about SCI munication and munication. The result of
these experiments indicates that the two-core hardware frame could enhance operation
speed and the stability of puter remarkably.
