A Hybrid Model Reference Adaptive and Regressive‐Form Sliding Mode Control in Discrete Domain: Robustness Under System Uncertainty

Engineering Reports, Volume 7, Issue 12, December 2025.
A novel MRASMC framework is developed, with a sliding surface derived from a regressive structure and parameters adaptively updated. An adaptive trigger condition enhances disturbance rejection without requiring complex observers or full system models.
