This paper discusses simultaneous design of a plant and controller for command responses, using two-degree-of-freedom control systems. First, we propose a new criterion for tracking performance, which are suitable for a simultaneous design problem. Next, we give a concrete design procedure of a feedforward controller, for a fixed plant. Numerical example demonstrates the effectiveness of the proposed criterion. It also shows that feedforward and feedback properties are not independent in case of simultaneous design.
