Distribution and Fault-Tolerance Control for Active Steering Bogie Based on Overdrive Characteristics
摘要
In this study, a distribution and fault-tolerance control strategy, based on overdrive characteristics, were proposed for active steering bogie. Two control layer was utilized in this strategy. Initially, the traditional geometric control (GC) strategy was utilized, facilitating the acquisition of the target wheelsets’ yaw angle in the control layer. Subsequently, under brake conditions or actuator failure, the actuator's displacements were redistributed within the distribution layer. The results demonstrated that the proposed control strategy could facilitate coordinate control with either traction or brake conditions, thereby enhancing steering efficiency. Furthermore, in the event of a failure, it was found that this strategy could ensure the bogie's running safety.
