Chattering Analysis,nisms, sensors and data processors with small time constants. Second, in digital control systems, microcontrollers having finite sampling rates are used, which causes so called ‘discretization chattering’. In this chapter, the first case, chattering in the presence of unmodelled dynamics, is discussed.

Practical Higher Order Sliding Mode Control: An Optimal Control Based Approach with Application to d. To overcome this Problem, one can replace the “sign” function in a small vicinity of the surface by a smooth approximation; this implies deterioration of accuracy and robustness. Note also that there are other approaches to reduce the effects of the chattering, by using either observers [35], or generalized sliding mode controllers [33].
