## NONSMOOTH L-TWO GAIN ANALYSIS OF TWISTING CONTROLLER

Luis T. Aguilar, Yury Orlov, Israel Ponce
The present work extends the $\mathcal{L}_2$-gain analysis towards sliding mode dynamic systems and it is tested on the twisting algorithm to illustrate that the resulting closed loop system is capable not only of rejecting matching uniformly bounded disturbances, but also of attenuating unbounded ones.
