Design an Active Suspension System Utilizing Intelligent Control Techniques
摘要
This study investigates the implementation of advanced control strategies for active suspension systems in automobiles. Given the increasing demand for improved ride comfort, safety, and fuel efficiency, the automotive industry has shifted toward more sophisticated suspension technologies. While fully active suspension systems offer superior performance, they often come with higher costs and energy consumption. To address these challenges, this research proposes a control strategy using MATLAB/Simulink for a quarter-car vehicle model. By comparing various control algorithms, including proportional integrative derivative (PID), fuzzy logic controller (FLC), and/or model reference controller (MRC), the study aims to identify the most effective approach for minimizing road vibrations and enhancing overall ride quality. Simulation results demonstrate a significant reduction in road vibrations (approximately 30%) when employing an active suspension system compared to a passive one. The findings of this study contribute to the ongoing development of more efficient and cost-effective active suspension systems, ultimately improving the driving experience for vehicle occupants. Future research directions include exploring alternative control algorithms, refining model complexity, and considering real-world factors such as tire dynamics and nonlinear suspension components.
