Abstract In this work, we have proposed a new accelerated adjustable predefined‑time (PDT) nonsingular sliding mode control approach for nonlinear systems (NLS). Based on the concept of adjustable predefined‑time stability (PTS), we have first established an accelerated inequality condition and given a complete theoretical proof to ensure the desired temporal convergence. This adjustable PTS accelerated lemma is then seamlessly integrated into a new accelerated sliding mode control architecture.
