报告内容简介：
    Sliding mode control (SMC) is a discontinuous control, aiming to create the so-called sliding mode by changing control structures.  An infinite switching frequency is usually required to maintain an ideal sliding mode. SMC has been extensively studied over the last sixty years due to its simplicity and robustness. It is well known that when SMC is implemented digitally, phenomena such as chattering and chaos may occur due to limited sampling rate for discretization.

    In this talk, we will explore discretization behaviors in SMC systems and evaluate the disrectization effect on SMC. We will show that under certain conditions asymptotical stability of the discretized SMC systems can be guaranteed and upper bounds of the eventually convergent system states can be analytically computed. We will also show various periodic trajectory patterns and their intrinsic properties using the symbolic dynamics approach.
