Abstract
Discretization effects in single input equivalent control based SMC systems of arbitrary dimension are studied. A bound for the number of iterates a trajectory may stay on one side of the sliding surface is found. Conditions for existence of periodic orbits are formulated. It is confirmed in simulations that even for very small values of discretization steps complex behaviors including periodic solutions of various length may be observed.
