摘要

Vehicle suspension systems are essential elements that ensure driver comfort and handling efficiency. This study examines the dynamic modelling of a semi-active suspension system for a half-car roll model equipped with a driver seat, utilising Proportional-Integral-Derivative (PID) control techniques. This study employs PID control methodologies within a half-car roll model to determine the optimal control approach for enhanced ride comfort and vehicle handling. The Semi-Active Suspension System utilising PID controller methods is evaluated against passive suspension systems based on peak value, rise time, settling time, overshoot, and RMS parameters concerning sprung mass acceleration, sprung mass displacement, sprung mass velocity, seat acceleration, and seat velocity. The simulation results show that the PID-controlled system significantly improves ride comfort and stability, outperforming conventional passive suspension systems on settling time and RMS values. The study's findings show that the PID-CC technique performed better than PID-ZN and the traditional PID method.
