This paper proposes an adaptive process noise covariance Kalman filter (APNCKF) for
detecting the power quality disturbances present in distorted power signals. Based on the …

This paper explores the practical application of the Kalman filter to the analysis of harmonic
levels in power systems. The merits and limitations of different possible implementations are …

With the ever-stringent vehicles exhaust emission standard and higher requirements on on-
board diagnostic technology, the importance of misfire detection in vehicle emission control …

Misfire detection in an internal combustion engine is very crucial to maintain optimum
performance throughout its service life and to reduce emissions. The vibration of the engine …

Vibrating structures may be subject to changes throughout their operating lifetime due to a
range of environmental and technical factors. These variations can be considered as …

The application of artificial intelligence methods in fault diagnosis is becoming more and
more extensive, and exploring and researching intelligent fault diagnosis methods for …

Conventional misfire diagnosis techniques are based on the analysis of the instantaneous
engine speed. Although they have proved their efficiency in some operating conditions and …

Great efforts have been made to resolve the serious environmental pollution and inevitable
declining of energy resources. A review of Chinese fuel reserves and engine technology …

Misfire is another type of abnormal combustion. When engine misfires, cylinder (or cylinders)
is not producing its normal amount of power. Engine misfire also has negative effects on …

This paper presents an algorithm for the detection of single and multiple misfires in internal
combustion engines, using only the signal of the knock sensor. Several experiments were …
