This paper presents a design method of optimal servo systems with frequency weights from the view point of the inverse LQ problem. This design method allows us to assign desirable closed-loop transfer functions directly and in addition, to obtain the desired optimal control law in a closed form in terms of design parameters and the system parameters. A numerical example is also shown to illustrate the design method proposed here as well as to show its usefulness.
