FPGA在吊丝微重力系统控制器中的应用

The application of field programmable gate array to the controller of a silk microgravity system

为达到吊丝微重力系统的性能要求,该文基于X ilinx公司V irtex系列芯片,采用VHDL硬件描述语言实现了遗传算法,并将其用于PID参数的优化。该方法集成了软件算法和硬件电路的优势,相比基于PC的遗传算法,在提高系统反应速度,抑制超调方面有所改善。

In order to meet the requirement of a silk mierogravity system, the paper presents the implementation of the genetic algorithm based on the virtex series chip of the Xilinx Co. with VHDL, which is a kind of hardware description language. This algorithm is used in the parameter optimization of PID. This method integrates the predominance of both software algorithm and hardware circuit. It is more efficient than the PC-based genetic algorithm in shortening the system response time and restraining overshoot.
