Chattering phenomenon is inevitable in most sliding-mode controllers due to finite switching or imperfect switching. Even under perturbation-free condition, chattering is still inevitable as well. This present work proposes a scheme that can guarantee a one-sided behavior performance and chattering-alleviated performance with uncertainty of known bounds of the plant. This scheme is applied to an optical pick-up head positioning system to illustrate its feasibility. Simulation study is performed to validate its effectiveness.
