模糊-PID复合控制器的FPGA实现

Fuzzy-PID Compound Controller Realized on FPGA

设计了一种利用FPGA(Field Programmable Gate Array)技术实现模糊-PID复合控制器的自顶向下的模块化硬件方案.该控制器能够将模糊-PID复合控制器的灵活性与硬件的实时性有效地结合起来,很好地克服了传统模糊-PID复合控制器实时性较差的问题,同时可以将该控制器扩展为多通道控制器,能够很好地解决多通道工业控制的实时性问题.通过VHDL(VHSIC(Very High Speed Integrated Circuit)Hardware Description Language)仿真分析,证明了该方法的有效性.

A hardware design scheme based on FPGA is presented to realize fuzzy-PID compound controller.The controller,which combines good flexibility built by fuzzy-PID controller with the real-time characters built by FPGA well,can be restructured as multi-channel controller to real-time solve the problem of multi-channel fuzzy-PID compound controller.By VHDL simulation,the improved version is proved to be effective.
