The study of self-oscillators dates back to Robert Willis, George Biddell Airy, James Clerk Maxwell, and Lord Rayleigh in the 19th century.  The term itself (also translated as "auto-oscillation") was coined by the Soviet physicist Aleksandr Andronov, who studied them in the context of the mathematical theory of the structural stability of dynamical systems.  Other important work on the subject, both theoretical and experimental, was due to André Blondel, Balthasar van der Pol, Alfred-Marie Liénard, and Philippe Le Corbeiller in the 20th century.

自激振荡器的研究可以追溯到19世纪的 Robert Willis、 George Biddell Airy、 James Clerk Maxwell 和 Lord Rayleigh。这个术语本身(也可以翻译成“自振荡”)是由苏联物理学家 Aleksandr Andronov 提出的，他在动力系统结构稳定性的数学理论的背景下研究了这些现象。其他关于这个主题的重要工作，包括理论和实验，是由于20世纪的 André Blondel, Balthasar van der Pol, Alfred-Marie Liénard 以及 Philippe Le Corbeiller 来完成的。

The same phenomenon is sometimes labelled as "maintained", "sustained", "self-exciting", "self-induced", "spontaneous", or "autonomous" oscillation.  Unwanted self-oscillations are known in the mechanical engineering literature as hunting, and in electronics as parasitic oscillations.Important early studied examples of self-oscillation include the centrifugal governor and railroad wheels.

同样的现象有时也被称为“维持”、“持续”、“自我激发”、“自我诱导”、“自发”或“自主”振荡。有害的自激振荡在机械工程文献中称为追逐，在电子学中称为<font color="#ff8000">寄生振荡 parasitic oscillations</font>。自激振荡早期的重要研究包括离心调速器和火车车轮。
