Saturated Super-Twisting Algorithm based on Perturbation Estimator

A Saturated Sliding Mode Controller based on Super-Twisting Algorithm and Perturbation Estimator is presented. With the implementation of the perturbation estimator, Saturated Super-Twisting Algorithm is able to use the entry range of control signal to compensate Lipschitz perturbations ensuring the global finite-time stability of the origin at the maximum rate of convergence that the saturated control signal can offer.
