Abstract

The servo control system driving a load through a flexible shaft or transmission system is widely used in industrial applications. Our purpose is to develop systematic analysis and design methods for two-inertia system. A conventional PI speed control system with a torsional load is redesigned, and the damping characteristic of the system is derived for a variety of inertia ratios. 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 analyzed and compared, and the merits of each pole assignment design are concluded. Furthermore for small inertia ratio, we present how to improve the damping by introducing a feedforward filter or a derivative feedback.
