PID制御による2慣性系の速度制御

抄録

The 2-mass system is the simplest model which generates a torsional vibration. In this system, two simple controllers are effective in suppressing the vibration. One is resonance ratio controller, and the other is PI controller with the first order lag filter.
This paper studies the 2-mass system controlled by a state feedback controller and clarifies that PID controller is able to determine the damping characteristics of the closed loop system in spite of its speed of response. In addition a new method to adjust PID controller is developed. Finally the above-stated two controllers are clarified to be the variations of PID controllers, because these controllers are designed only by adjusting parameters which determine the damping characteristics with the method.
