Simulation of Full-axle Steering Control Strategy for DRT
Journal Title: Urban Mass Transit - Year 2024, Vol 27, Issue 5
Abstract
Objective Digital rail transit of rubber-tyred train (DRT) features a complex running structure with multiple carriages and axles, significantly differing from conventional rubber-tyred trains. Therefore, it is necessary to design a full-axle steering control strategy based on the design and response parameters of the steering system to achieve smooth, safe, and efficient operation of DRT. Method Models of single-car, double-car, and multiple-car vehicles are established for DRT. By successfully simplifying the complex three-car model into a four-degree-of-freedom rigid body motion model, the steering control problem of DRT is transformed into a kinematic control problem for four control points. A full-axle steering control strategy for DRT is proposed. Result & Conclusion MATLAB software simulation results demonstrate that the proposed full-axle steering control strategy can limit the deviation of the motion trajectory of DRT within 10 cm.
