摘要
为了防止自行式集装箱拖车可能出现的打滑现象,对电力拖车制动防滑控制系统进行了仿真研究。根据轮轨粘着特性,建立了电力拖车减速过程的动力学模型。依据直接蠕滑速度防滑控制方法,分别设计了门限控制器和模糊控制器。仿真结果表明:采用防滑控制方法可以有效地抑制驱动轮过度滑移甚至抱死,模糊控制与门限控制相比,能更平滑地调节制动力矩,更好地将蠕滑率控制在期望值附近。
Simulation of anti -sliding control system for electrical trailer is conducted and deceleration dynamic model is built based on adhesive characteristics. A threshold controller and fuzzy controller are designed by means of direct creep speed anti - slide method. The simulation results show that the anti - sliding method mentioned in this paper can efficiently prevent driving wheels from sliding or lock. Compared with threshold controller, fuzzy controller can control braking torque more smoothly and can keep creep slide rate within a range of desired values.
