Review of: "Simulation of Control System for a Half-Car Suspension System for Passenger Vehicle Application by Designing an LQR Controller"
Résumé
The authors focused on the modeling and control of a passenger half-car suspension system.A mathematical model for a linear 4-DOF car suspension system was built and derived under dynamic conditions.A chosen controller was then used after the dynamic model had been created, and its performance was evaluated at various vehicle speeds while being subjected to input disturbances from bumpy roads.The effectiveness and performance of the controller were verified by simulation using MATLAB/Simulink.In the vertical direction, peak-to-peak, the active suspension system (ASS) with an LQR controller improves performance.Additionally, sprung masses tilting in the lateral direction improved.The new design with an LQR controller successfully controls the dynamic effect in both expected and random road inputs.In the Simulink graph, the controller provides improved comfort in the vertical and lateral directions and good handling at the two wheels.Paper has a very good contribution in the respective field.Overall, the paper has innovation and significant contributions.
