A properly functioning brake system is critical for ensuring the safe operation of any vehicle on roadways. Commercial vehicles
such as trucks, tractors-trailers and buses are equipped with an air brake system that uses compressed air as the energy transmitting
medium. This paper presents a model-based control scheme for an electropneumatic brake system for use in commercial vehicles.
A mathematical model for an electropneumatic brake system was developed and corroborated with experimental data. A control
scheme was developed based on this model and was used to regulate the pressure of air inside the brake chamber according to
a desired pressure trajectory. This control scheme was implemented on an experimental test bench, and its performance was
studied for various values of the controller parameter. The control scheme was tested for various desired pressure trajectories
reflecting actual brake operation. 相似文献

For off-road vehicles, minimizing the absorbed power is the main objective of suspension control. The primary cause of increase in the absorbed power in off-road vehicles driven at high speeds on harsh courses is the exhaustion of the suspension travel. Fuzzy-logic approach to active and semi-active off-road vehicle suspension control, with the goal of improving the speed of the vehicle over rough terrains are developed. The ride metric used for quantifying improvements is the absorbed power of the sprung mass. Particular attention is paid to the proper modeling of the suspension using both the full kinematic constraints and the more convenient two degree of freedom linear model of the quarter vehicle suspension. The nonlinearities due to the kinematic constraints on motion are accounted for by modifying the stiffness and damping coefficients of the suspension spring and dashpot in the linear model. The control laws are developed using the less complex model and demonstrated in the fully constrained environment. Nonlinearities of the suspension, including tire stiffness/damping and bumpstops are included at all stages of controller development. 相似文献
