This paper performs an analysis of switching time abut sliding mode controller. A mathematical method for determining and analysis the switching frequency about the sliding line are declared. A contribution to the SMC implementation based on Variable Structure Controllers (VSC) was adapted to analysis the chattering phenomenon and estimate the switching time of sliding mode controller. Also shows the behavior of switching frequency and find the relation between the switching intervals with the magnitude of the gain. The simulation results should be significance to design engineers who wish to express and study experience in control methods and their applications.
