A Design Method of Optimal H2 Integral Servo Controller for Torsional Vibration System

This paper proposes a design method of optimal H2 integral servo controller. The optimal H2 integral controller is to establish a way to find the admissible controller such that the controlled plant is stabilized and guarantee to track a constant reference signal while minimizing the close-loop system H2 norm from the disturbance to the controlled output. In this paper the derivative state constrained optimal H2 integral servo controller is proposed for oscillatory system with a constant disturbance. This design method has the advantage that it can be applied to reduce the vibration of the two-inertia system. The effectiveness of proposed controller is evaluated by experiments.
