Abstract :
A novel chattering alleviation control (CAC) algorithm is proposed for variable structure systems (VSSs). Both analog and digital controllers using the theory of CAC are applied to the position control problem of a DC servomotor system. Comparisons of the CAC with other VSS control algorithms indicate that the chattering can be alleviated. Since the input of the CAC method contains only low-frequency components, it will not excite unmodeled high-frequency plant dynamics
