Condition Monitoring based Control using Wavelets and Machine Learning for Unmanned Surface Vehicles Abstract: This paper proposes the idea of fault detection and diagnosis for stable operation of unmanned surface vehicles (USVs). The idea of fault classification is achieved with the help of wavelet transforms and support vector machines, and ...
Currently, surface defect detection of stamping grinding flat parts is mainly undertaken through observation by the naked eye. In order to improve the automatic degree of surface defects detection in stamping grinding flat parts, a realtime detection system based on machine vision is designed. Under plane illumination mode, the whole region of the parts is clear and the outline is obvious ...

Increasing interest has been seen in condition monitoring (CM) techniques for electrical equipment, mainly including transformer, generator, and induction motor in power plants, because CM has the potential to reduce operating costs, enhance the reliability of operation, and improve power supply and service to customers. Literature is accumulated on developing intelligent CM systems with ...
The use of statistical methods for anomaly detection has become of interest to researchers in many subject areas. Structural health monitoring in particular has benefited from the versatility of statistical damagedetection techniques. We propose modeling structural vibration sensor output data using nonlinear timeseries models.
Grinding machine condition monitoring is very important during the manufacturing process. Vibration analysis is usually used to its pattern recognition. But traditional signal analysis method limits the accuracy of recognition because of nonstationary and nonlinear characteristics. In this paper, a novel approach is presented in detail for grinding machine fault diagnosis.

Vibration based condition monitoring is the process in which the machine components are regularly checked and the condition, whether it is healthy or faulty, is checked on the basis of vibration signals got from the machine components. Vibration monitoring can be broadly carried out at three levels [1]: 1.
Condition monitoring is the process of determining the condition of machinery while in operation. The key to a successful condition monitoring programme includes: Knowing what to listen for; How to interpret it; When to put this knowledge to use; Successfully using this programme enables the repair of problem components prior to failure.
