基于FPGA的模糊PID控制器的设计

Design of Fuzzy PID Controller Based on FPGA

本文提出了一种基于VHDL描述、FPGA实现的模糊PID控制器的设计,使用自顶向下的设计流程完成了控制器的VHDL设计,并在一个具体的FPGA芯片上实现了该控制器。由于采用了模糊自整定参数技术和增量式PID算法,本设计既降低了FPGA的资源耗费,又改善了传统PID控制器的控制性能。

A design of fuzzy PID controller based on VHDL and implemented by FPGA is proposed.The VHDL design of the controller is finished with the top-down design flow,and is downloaded into a FPGA chip.By use of fuzzy self-tuning technology and incremental PID algorithm,this design has a much better performance than the custom PID controller and reduces quite a lot of hardware consumption.
