A Chattering-Free Sliding Mode Filter Enhanced by First Order Derivative Feedforward

A Chattering-Free Sliding Mode Filter Enhanced by First Order Derivative Feedforward

Noise reduction is one of the important issues for feedback control systems. Toward this problem, this paper proposes a new sliding mode filter, which is an improvement of Lv et al. 's parabolic sliding mode filter. The proposed filter employs a first-order derivative feed-forward term for incr...
