Integrated adaptive velocity and semi-active suspension control for different road profiles

Abstract

This study represents the integrated comfort-oriented velocity design, tracking control, and adaptive semi-active suspension control method. The velocity design approach is based on the ISO 2631-1 standard, while the proposed velocity tracking control method is based on the LPV control architecture. A road adaptive semi-active suspension control method, where a trade-off between vehicle stability and driving comfort is accomplishable to achieve desirable performance results at different road profiles and velocities. The trade-off is accomplishable due to flexibility and online reconfigurability of the LPV control method by online modification of scheduling variables. The design is based on the performance index, road profile, and the designed velocity of the velocity. The velocity designer, velocity tracking controller, and adaptive suspension controller have been integrated and simulated in the TruckSim environment to show the operation of the proposed method.
