Abstract

The active suspension system plays a crucial role in meeting the growing demand for enhanced vehicle ride comfort. This paper introduces a higher-order Sliding Mode Control algorithm (HOSM-AD) designed to effectively address actuator delay issues, thereby improving both ride comfort and vehicle robustness. Initially, An advanced active suspension model has been developed that incorporates actuator delay. The delay characteristics of the actuator and the state output of the suspension model are used to define the error surface, on which a higher-order sliding mode surface is constructed. This approach aims to enhance the robustness and responsiveness of the suspension system. Simulation results demonstrate the effectiveness of the algorithm in improving vehicle dynamics performance under various operating conditions, highlighting its superior smoothness and robustness.
