Abstract

This seminar presents key developments in modern sliding mode control with emphasis on continuous and higher-order techniques. It discusses the super-twisting controller as a representative algorithm enabling robust performance with smooth control action. Attention is given to closed-loop performance analysis, including frequency-domain perspectives and the design of compensating filters for sliding mode control systems. The seminar also introduces barrier function–based adaptive sliding mode controllers, highlighting their role in handling uncertainties and performance constraints. Overall, the talk provides an integrated view of analysis, design, and recent methodological advances in modern sliding mode control.
