基于FPGA和DMC算法的无叶风扇的设计

Design of Bladeless Fan Based on FPGA and DMC Algorithm

提出一种以FPGA处理器为核心的无叶风扇,分别做系统的硬件设计和软件设计,并把动态矩阵控制算法(DMC)应用于风扇的气压控制,达到调整风扇风速的作用。结果表明,DMC控制能够使输出气压迅速跟踪设定气压,可获得较好的稳定性和准确性,该方法能适应其它类似参数的控制。

The paper introduces the bladeless fan with kernel of FPGA processor and presents the practical design of hardware design and software design. The paper elucidates the application of DMC algorithm to control the air pressure of the fan, in order to adjust fan speed. The results show that DMC can make output pressure quickly follow the tracks of setting pressure, and achieve better stability and precision. The method also adapts to the control of other parameters.
