摘要
本文提出了一种基于模糊控制的直流电机脉宽调制(PWM)调速系统。该系统将转速偏差和转速偏差率模糊化为模糊控制器的输入语言变量,根据所制定的一套模糊控制规则来选择控制PWM中开关管IGBT导通时间的输出语言变量,并以此通过脉宽调制技术来驱动直流电机。仿真实验结果表明该系统能有效的抑制超调现象,提高系统的响应速度和稳态性能。
This paper proposes a pulse width modulation （PWM） speed regulating system of DC motor based on fuzzy control. The speed error and its change were used as fuzzy stable variable. According to a set of fuzzy rules, the output Variable was selected to control the IGBT switch, In this way, the PWM technique was used to drive the DC motor. The simulation results showed that the system could depress the overshoot and improve the response and steady state performance.
