Abstract

This seminar presents the evolution of Sliding Mode Control through five generations developed over the past decades. It outlines the progression from classical first-order discontinuous controllers to higher-order, continuous, and nested sliding-mode algorithms. A key focus is on how successive generations improved convergence properties, reduced chattering, and enhanced robustness for systems with higher relative degree. The seminar provides a structured and conceptual overview of the major milestones that have shaped modern sliding mode control and its current form.
