Abstract
The purpose of this work is to identify stability margins in systems controlled by Sliding Mode Control (SMC)/High Order Sliding Modes (HOSM). The proposed stability margins characterize robustness of SMC/HOSM against parasitic dynamics and allow to certifying the performance of systems controlled by SMC/HOSM in different applications. An example with third order HOSM control algorithm is presented. The proposed technique is confirmed via phase and gain margin identification for systems with third order HOSM control.
