Abstract

This paper focuses on a novel robust finite-time control for active suspension systems with external disturbance where the control inputs are naturally bounded by a prior known range to avoid input saturation. To achieve finite-time stability, a novel nonsingular terminal sliding mode variable with an integral term is designed. More importantly, the control inputs are naturally bounded all the time due to the characteristics of hyperbolic tangent functions such that extra saturation compensation methods can be avoided. A disturbance compensation technique is deliberately designed in the proposed control to enhance the robustness of the system while the bounded property can be ensured simultaneously. The whole control structure is relatively simple yet effective compared with existing control techniques which is much easier to implement in practical active suspension systems. Additionally, the overall stability of the closed-loop system is verified by the Lyapunov theorem. Various simulation results are provided to demonstrate the robustness and effectiveness of the proposed control design. © The Author(s), under exclusive license to Springer Nature Singapore Pte Ltd. 2024.
