## Abstract This paper presents a new appoach based on the use of describing functions to obtain approximate symbolic expressions for the fundamental frequency component as well as for the second‐ and third‐order harmonics. A single soft or hard transconductance non‐linearity embedded in an arbitra
Two H optimization problems of a nonlinear tracking control system: the problem of a nonlinear controller and the problem of a nonlinear plant are considered in the paper. The describing function method is used for linearization of a feedback control system. Theorems, which enable one to replace the
