Fuzzy Adaptive Optimization Prescribed Performance Control for Nonlinear Vehicle Platoon

Predefined-Time and Prescribed-Performance Control Methods Combined with Second-Order Terminal Sliding Mode Control for an Unmanned Planing Hull System with Input Delay and Unknown Disturbance

“…However, as another constraint control method, prescribed-performance controls [38][39][40][41][42] are considered to obtain greater robustness to unmatched pitching-moment disturbances without requiring a complex disturbance observer in this study. Prescribed-performance control implies that the tracking error should converge to an arbitrarily prescribed small steady state bound with an appropriate convergence rate and exhibit a maximum overshoot of less than a sufficiently small predefined value.…”

“…In this study, based on the idea that the robustness of the control system with the prescribed-performance control can partially exert a disturbance depression, the prescribed-performance control applied in [42] was adopted without explicit dependence on the disturbance observer. The adopted prescribed-performance control term requires a simpler variable transformation than that presented in [36][37][38][39][40][41]. Notably, the predefined control performance can be achieved by adding the prescribed control term.…”
