The synthesis of optimum systems from nonideal components

THE USEFULNESS of statistical techniques in the synthesis of optimum control systems has been amply justified,1¿7 and a voluminous literature exists on the subject. A wide class of such synthesis problems are those where the basic circuit is fixed and the designer must choose values for a finite number of parameters. It is usually assumed that these parameters relate to components which possess exactly their nominal values. In such cases, once a design criterion has been established, the optimization procedure is straightforward.
