“…Unfortunately, they are open-loop methods that require special signal generators, and they are either too restrictive or too sensitive. A completely new approach for frequency-based closed-loop identification of Hammerstein-type plants is described in [17], [18], [19] and [20]. However, nothing similar is presented so far for the Wiener-type plants.…”

This paper proposes a new closed loop frequency based method for a parametric identification of some types of Wiener-type nonlinear plants. It provides a parametric model of the linear part of the plant, and a point by point relationship between input and output of the nonlinear part of the plant. Two approaches are proposed for the identification of the nonlinear part. The first approach is slower, but it does not require any additional equipment expect the relay. The second approach is much faster, but it requires some additional equipment.
