Design of automatic voltage-regulating system based on fuzzy-PID control in host link computer

针对电机实验室常用三相调压器的不足,提出了一套在上位机利用模糊PID控制算法驱动伺服机构的调压方案,实现了使三相调压器的输出快速稳定达到上位机软件设定值的功能。系统具备了优良的动、静态性能,并能够克服因电网电压的波动所引起的扰动。最后,通过实测的三相调压器输出波形论证了系统的可行性。

Considering the shortcomings of the conventional three-phase voltage regulator in the electrical laboratory, a method based on fuzzy-PID control in the host link computer is proposed to drive servo mechanism to realize voltage-regulating. This method can make the output of three-phase voltage regulator reach the set point fast and steadily. Moreover, good static and dynamic performances and the ability to overcome the disturbance caused by electrified wire netting are realized, finally, the measured output of three-phase voltage regulator demonstrates the feasibility of this method.
