要約(英語): In this paper, a new feed-back controller reduction scheme is proposed. The two-degree-of-freedom(2DOF) control system has a feed-forward controller and a feed-back controller, thereby expanding the range of feasible transfer characteristics. However, this increases the overall order of the controller. It is necessary to reduce the order in the implementation of the controller. In 2DOF control systems, it is known that the transmission characteristics change when the plant changes. A method using the Riccati equation is employed to reduce the order of the feed-back controller preserving the transfer characteristics. A numerical example is illustrated to show the effectiveness of the method.
