    The sub-class of Lur'e systems studied by Popov is described by: ˙ = + ˙ = = + = where x ∈ R n, ξ,u,y are scalars, and A,b,c and d have commensurate dimensions. The nonlinear element Φ: R → R is a time-invariant nonlinearity belonging to open sector (0, ∞), that is, Φ(0) = 0 and yΦ(y) > 0 for all y not equal to 0.
