可控硅直流调速系统大家已相当熟悉了。然而,过去大家接触最多的是一般具有速度负反馈和电流截止反馈的系统,加上各种微分反馈作稳定校正,或是电压负反馈加电流正反馈组成的速度反馈系统。而现在介绍的是一个具有速度负反馈、电流负反馈的调速系统。过去,一般认为电流负反馈对系统的静态特性有极坏的影响,近年来,随着电子工业的飞速发展,集成电路线性放大器等器件的出现,电流负反馈出现了新的理论,可忽略其对静特性的影 SCR DC speed control system we are already quite familiar. However, in the past, the most commonly used system is the system with speed negative feedback and current cutoff feedback, plus various differential feedbacks for stable correction, or the negative feedback plus current positive feedback system. Now introduced is a speed negative feedback, current negative feedback speed control system. In the past, it is generally considered that the current negative feedback has a very bad influence on the static characteristics of the system. In recent years, with the rapid development of the electronics industry, the appearance of devices such as integrated circuit linear amplifiers, current negative feedback presents a new theory, Shadow on the static characteristics
