Abstract
This paper aims to develop a prescribed performance fast terminal sliding mode control (SMC) strategy for active seat suspension systems under road disturbances and lumped uncertainties.
A hierarchical control architecture is developed, in which a prescribed performance framework is integrated with fast terminal SMC to generate the desired actuator force for vibration suppression, while cascaded proportional-integral-derivative controllers are used for hydraulic force tracking and spool-valve regulation. Numerical simulations are conducted under ISO C-class and ISO D-class road excitations.
The proposed controller achieves the best vibration attenuation performance among the compared methods. The maximum seat displacement and acceleration are limited to 0.72 mm and 0.08 m/s2 under ISO C roads and 0.91 mm and 0.10 m/s2 under ISO D roads.
This study presents a novel integration of prescribed performance control and fast terminal SMC, providing enhanced ride comfort and robustness for active seat suspension systems operating in uncertain road environments.
Vehicle suspension systems play a crucial role in ensuring ride comfort, stability, and safety under varying road conditions. While conventional passive suspensions offer limited adaptability, active suspension systems dynamically regulate actuator forces to counteract road-induced disturbances and improve overall perf...

This paper presents a dual-accumulator hydraulic active suspension (DAHAS) system capable of switching between active and semi-active modes. Unlike conventional designs, the proposed actuator integrates a motor-pump unit (MPU) for low-frequency vibration control (below 5 Hz) and a dual-valve continuous damping control...
