Recently, a new design method of optimal servo systems, called “ILQ Method”, has been developed by applying the pole placement method. This paper treats its generalization for relaxation of a restriction imposed on the system in its original version. By a natural extension of the selection method of design parameters as well as the pole placement algorithm, the restriction can be relaxed significantly. Under a relaxed condition, the design parameters can be chosen so as to specify each output response in a certain class, and in addition, the optimal gain achieving such specified output responses can be expressed explicitly in terms of the system matrices and the design parameters. Some numerical examples are also illustrated to show the validity of the design method.
