In this paper, we propose a new reduction method of the feed-forward controller. In the method we employ the block balanced truncating technique which can consider the structure of the control systems. The block balanced truncating method are usually used for the feed-back controller reduction. But it is also applicable to reduction of the other subsystems. The two-degree-of-freedom control system has the feed-forward controller to expand achievable transfer property. Reduction of the feed-forward controller can contribute for simplification of control systems totally. A numerical example is illustrated to show the effectiveness of our method.
