This paper presents an application of adaptive 2nd order slid- ing mode control. This control is based on twisting algorithm. The control solution required a limited infor- mation about the uncertainties and the disturbances acting on the system. This control strategy is applied to an electropneumatic set-up. This bench consists of two rod coupled pneumatic cylin- ders: one cylinder is controlled on position and perturbed by the second cylinder which is force-controlled. The efficacy of this strategy is evaluated through some simulations.
