| 摘 要： | 移动机器人并发故障诊断技术大多将并发的多故障作为多种单故障组合状态处理,这样不仅需要为每种故障设计滤波器,且只能诊断特定的多故障组合.为了克服这些缺点,提出一种移动机器人多故障并发的故障诊断技术.根据移动机器人的运动模型,为每一种单故障状态设计一个对应的卡尔曼滤波器,用这些滤波器对移动机器人并发故障数据进行滤波.利用模糊聚类方法对滤波结果进行分类,根据移动机器人运行数据对不同单故障集合的隶属度诊断任意组合的并发故障.在三轮移动机器人Pioneer3上进行仿真实验,对14种常见的单故障和多故障并发的情况进行诊断,证明了该方法对轮式移动机器人并发故障诊断的有效性.

| Abstract: | Most fault diagnosis methods for mobile robots that treat simultaneous multi-faults as a single fault state need to design a filter for each fault combination and can only diagnose the specific-set combinations of multi-faults presently. To overcome these disadvantages,a simultaneous faults diagnosis method for mobile robots was proposed. According to the kinematic model of a mobile robot,a specific Kalman filter (KF) was designed for each single fault state to filter the fault data of the mobile robots. Re... |
