Keyword齿谐波 数字信号处理 谱估计 转速估计
Abstract基于齿谐波检测来估计转速的方法由于其不依赖于电机参数的优越性而受到关注。本文采用数字信号处理技术实现齿谐波信号的提取,并利用混叠技术来提高齿谐波谱峰的识别。通过对比不同的谱估计方法展开齿谐波频率分辨能力的研究。实验结果表明最大熵谱估计方法在精度上有所提高且在实时性上也获得更好的性能。
Other AbstractBecause of the independence of time-varying motor parameters,the method of speed estimation based on rotor slot harmonics (RSH) has brought much concem.In this paper,Speed information of RSH is extracted by digital signal-processing techniques.And what's more,the peak detection of RSH can be enhanced by using the aliasing technique.By comparing various spectral estimation methods,researching the resolving capability of frequency of RSH.Experimental results show that the method of maximum entropy spectral estimation (MESE) has more advantage in accuracy and real-time.
