Comparing the Performance of Active and Passive Suspension Systems for a ¼ Vehicle using MATLAB/Simulation

Abstract We sincerely believe that the suspension system significantly guarantees comfort and driving safety in various scenarios and road conditions since it only connects the vehicle to the occasionally uneven road. Thus, the performance of two distinct suspension systems, passive (PSS) and active (ASS), was the main focus of this investigation. The MATLAB/Simulink environment models and simulates a representative vehicle in a two-degree-of-freedom system. By utilizing software modeling and simulation, it is possible to understand how the two systems behave under identical conditions and parameters by analyzing the differential motion equations that describe them. Numerical and graphical findings comparing the two systems demonstrated that the ASSs with controllers perform better than the traditional systems in terms of suspension system adjustment and response time (rising time, overshoot, settling time, and steady-state error). It also reduces roll and pitch movements, dissipates vertical oscillations, and reduces dissipation, which was the research's main objective.
