Abstract :
Zero-order holder discretization effects in sliding mode control systems with an input delay are studied. Conditions for the existence of periodic solutions are derived and the existence of periodic steady states is investigated. The influence of the discretization step and the delay on the period and the amplitude of steady state oscillations is studied. Simulation results are presented to show the structure of basins of attraction of periodic orbits with different switching patterns.
