Abstract :
Zero-order holder discretization of two-dimensional sliding mode control system is studied. Steady-state behaviors are classified and their bounds are found. Conditions under which the system trajectory in the steady state spends at most two iterations on each side of the sliding surface are presented. The existence of complex switching patterns for arbitrarily small discretization steps is confirmed. Theoretical results are illustrated with simulation examples.
