Abstract :
Two discretization methods for a simple sliding mode control system are studied in detail. It is shown that for arbitrary discretization step the zero-order holder discretization is equivalent to the Euler discretization with a smaller value of the discretization step. A complete diagram of admissible short periodic orbits is found and structure of periodic orbits is analyzed.
