摘要

我们的目的是发展双惯性系统的系统分析和设计方法。对具有扭转载荷的传统PI调速系统进行了重新设计，推导并分析了该系统的阻尼特性。结果表明，系统的动态特性在很大程度上取决于负载与电机的惯量比。对具有相同半径/阻尼系数/实部的三种典型极点配置进行了比较，总结了每种极点配置设计的优点。此外，对于较小的惯性比，我们展示了如何通过电机速度的导数反馈来改善阻尼。

Speed control of two-inertia system by PI/PID control

Our purpose is to develop systematic analysis and design methods for a two-inertia system. A conventional PI speed control system with a torsional load is redesigned, and the damping characteristic of the system is derived and analyzed. It is shown that the dynamic characteristic of the system strongly depends on the inertia ratio of load to motor. Three kinds of typical pole assignments with identical radius/damping coefficient/real-part are applied and compared, and the merits of each pole assignment design are concluded. Furthermore, for small inertia ratio, we show how to improve the damping by a derivative feedback of motor speed.
