基于FPGA的静力加载谱生成与控制算法研究

静力加载试验谱是根据静力加载试验中的载荷表形成的加载谱形,由不同的目标值和其它参数组成;试验加载谱的生成过程指按规定时间和曲线类型运行到指定值的过程;针对当前静力加载试验中对加载谱控制的多功能要求,参照主流控制系统中上位机的操作流程,实现了一种基于FPGA的加载谱生成与控制算法,满足现有控制系统中试验加载谱的生成模式和各种命令的操作,包括连续加载谱的生成、谱的单步调节、单点控制、选择谱段控制和控制方式切换等,配合系统控制算法为自主控制器的开发奠定基础.

The generation and control algorithm of static loading test spectrum based on FPGA

The static loading test spectrum is the loading spectrum formed according to the loading table in the static loading test, which is composed of different target values and other parameters. The generation process of test load spectrum refers to process of running to the specified value according to the specified time and curve type. Refer to the upper computer in the current mainstream control system. The operating process realizes an algorithm of generation and controlling the load spectrum based on FPGA, which satisfies the operation of the test load spectrum and command in the existing control system. It includes the generation of the continuous loading spectrum, the single-step adjustment of the spectrum, the single-point control, the selection of the spectrum segment control and other operations, so as to lay the foundation for the development of the autonomous controller.
