- Summary:
- The suspension system, as a critical component of vehicle chassis, connects body frame and wheels, therefore affecting the ride comfort and handing stability of vehicles. To prevent high-frequency oscillations from large control increments of traditional algorithms, an ideal reference model is introduced to ensure a more smooth and efficient suspension responses that align with actual physical characteristics. The ideal skyhook, ideal groundhook, and ideal skyhook-groundhook models are evaluated with respect to their frequency response. As a result, the optimal configuration-ideal skyhook-groundhook model, exhibits the best overall performance and is incorporated with wheelbase preview mechanism as reference model (WP-SHGH). Further, a wheelbase-preview controller based on MPC framework (WPMPC-SHGH) is developed to regulate the responses of semi-active suspension. The Adams/Car-Simulink co-simulation platform is built for validation and comparison on the impact and ISO-B random roads. Compared to the passive suspension and the similar controller without reference model, the proposed WPMPC-SHGH significantly reduces vertical acceleration and pitch acceleration of vehicle body, which thereby enhances vehicle ride comfort. In addition, while maintaining suspension performances, the WPMPC-SHGH anticipates less control forces and leads to a reduction in energy consumption of semi-active suspension
