基于FPGA的模糊PID控制器设计

Design of fuzzy PID controller based on FPGA

针对模糊PID控制器多为单片机技术的软件实现,其实时性与抗干扰性能不理想,采用以FPGA作为核心控制器,采用模块化思想,设计并实现模糊自适应PID控制器的硬件设计方案。实际运行结果表明,采用该方法可明显改善效果,在简化设计的同时,也可提高系统的实时性和抗干扰能力。

Considering the fuzzy PID controller is almost realized by single chip microcomputer software programmed,the real-time and anti-jamming are poor.This paper uses FPGA as the core controller and adopts the idea of module,a hardware design scheme is presented to realize adaptive PID controller.The practical operation result shows that this method can significantly improve the control effect,and also improve the computational speed and reliability of the system while simplify the design.
