Abstract
The purpose of this paper is to develop systematic analysis and
design methods for a two-inertia system. A conventional
proportional-integral 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 present
how to improve the damping of the system by a derivative feedback of
motor speed
