摘要
由于独立旋转车轮的直线对中和曲线导向能力差,文章以牵引电机导向型独立旋转车轮为研究对象,开展导向控制策略的研究。针对横向位移控制在系统参数变化后,PID参数需要重新整定的问题,提出基于模糊逻辑控制的参数自适应调整策略。此外,考虑到导向转矩的实现依赖于轮轨间黏着力,在优化黏着控制的基础上提出考虑黏着限制的转矩分配策略。通过仿真软件MATLAB与Simpack搭建机电耦合仿真模型,对提出的控制策略进行验证。结果表明,在系统参数变化和轨面状态变差的情况下,独立旋转车轮仍具有较好的导向能力。
Independently rotating wheels(IRWs)suffer from inadequate performance in lateral restoration and curve guidance.This paper focuses on studying the guidance control strategies,taking the IRWs driven by traction motors as the research object.To resolve the problem that the PID parameters need to be reset following any change in the system parameters for lateral displacement control,a parameter self-adaptive adjustment strategy based on fuzzy logic control was proposed.In addition,recognizing that the realization of guidance torque depends on wheel-rail adhesion,this paper proposed a torque distribution strategy that takes into account adhesion restrictions and was based on optimized adhesion control.Finally,the proposed control strategies were verified using an electromechanical coupling simulation model built with MATLAB and Simpack.The results show that IRWs still behave with good guidance ability to adapt to the changes in the system parameters and deteriorating track conditions.
