 abstract={In this paper, necessary conditions for the L2 optimality of a first-order-plus-dead time (FOPDT) model of a high-order plant are derived using classic analytic function theory. They are expressed as a set of three nonlinear equations that partly resemble the interpolation conditions valid for rational approximation. From these conditions a simple procedure to find the optimal FOPDT model is obtained. An example taken from the relevant literature is finally worked out. It turns out that the impulse and step responses of the L2-optimal FOPDT model fit well those of the original high-order rational system.},
