This paper develops a discrete-time sliding mode controller with a power rate exponential reaching law approach to enhance the performance of a pneumatic artificial muscle system in both reaching time and chattering r...
This paper proposes an adaptive integral higher order sliding mode (HOSM) controller for uncertain sys- tems. Instead of a regular control input, the derivative of the control input is used in the proposed control l...
