摘要
将广义区间概率与隐马尔科夫模型结合,建立了广义隐马尔科夫模型,使之具有更好的鲁棒性和处理2类不确定性问题的能力,并成功用于滚珠丝杠进给系统的轴承温升预测。结果表明,广义隐马尔科夫模型能够根据历史信息对轴承的温升进行预测。
The generalized hidden Markov model (GHMM) is proposed by combining the generalized interval probability and the HMM. In this hybrid approach,the model has better robusticity and better performance modeling the two types of uncertainty simultaneously. The result of prediction of bearing temperature rise was presented and the method is confirmed.
