An example of phase space partition. Partition of the phase space associated to a dynamical system with two state variables, where each variable x _i ∈ [0, ], i = 1, 2 is associated with two ordered thresholds θ _ij , j = 1, 2. The white rectangles denote regular domains. The gray rectangles denote switching domains, whose width, δ > 0 is a monotonic function of the parameter q with δ(q) → 0 for q → 0. In the light gray regions one variable is switching and the other one is regular, whereas in the dark gray ones both variables are switching.
