A Design Method of Derivative State Constrained H2 Integral Servo Controller for Suppressing under Damping of Oscillatory System
A design method in this paper concerns the optimal H2 integral servo problems for two-inertia model via the constraints of the derivatives of state variables added to the standard constraints. It is shown in the paper that the derivative state constrained optimal H2 integral servo problems can be reduced to the standard optimal H2 control problem. The main subject of the paper is to derive the derivative the theorem for state constrained H2 integral servo. The effect of our proposed controller with respect to reduce an under damping for two-inertia model system is also verified.
