利用模糊控制算法实现了一个小型直流电机的转速控制系统。用LabVIEW的模糊控制器设计工具进行模糊控制器的设计，通过NI-PCI6251完成实时速度采集以及电机转速控制。实际运行表明该系统具有超调小，调节时间短以及振荡小的优点。 -The use of fuzzy control algorithm to achieve the speed control system of a small DC motor. Fuzzy controller with fuzzy controller design tools in LabVIEW design through NI-PCI6251 complete real-time speed of acquisition, and motor speed control. The actual operation shows that the system has a small overshoot, adjust short time, and the advantages of small oscillations.
