Sliding Mode Control is a nonlinear control methodology based on the use of a discontinuous control input which forces the controlled system to switch from one structure to another, evolving as a variable structure system. This structure variation makes the system state reach in a finite time a pre-specified subspace of the system state space where the desired dynamical properties are assigned to the controlled system. In the past years, an extensive literature has been devoted to the developments of Sliding Mode Control theory. This kind of methodology offers a number of benefits, the major of which is its robustness versus a significant class of uncertainties and disturbances during the sliding mode. Yet, it presents a crucial drawback, the so-called chattering, which may disrupt or damage the actuators and induce unacceptable vibrations throughout the controlled system. This may limit the practical applicability of the methodology, especially in case of mechanical or electromechanical plants. The problem has been faced by recent theoretical developments, oriented to increase the order of the sliding mode, thus producing effective Second Order and Higher Order Sliding Mode Control algorithms. These “modern” results can be profitably used to efficiently solve real world control problems, as testified by several recent publications and research projects. The aim of this seminar is to provide an outline of the mentioned theoretical advancements, and an overview of available examples of applications of sliding mode control to different fields, focusing on recent activities developed by the research group chaired by Prof. Ferrara at the University of Pavia.
