Measurement bias or drift often occurs after long-term use of the sensor. Measuring faults
will inevitably mislead the control system, making the goal of advanced control strategies …

Sensor technology is one of three major pillars of the modern information technology. With
the extensive application of sensor, the dependability of the sensor is paid more and more …

The possible faults of a sensor may be classified as abrupt (sudden) faults and incipient
(slowly developing) faults. This paper focuses on the abrupt faults of a sensor. Due to the …

This study describes a fault diagnosis system for mechatronics modules realized through the
combination of wavelet transformation, fuzzy logic and neural network techniques. As a …

Successful fault detection is based on effective feature exaction and selection processes.
Feature map is one of the current fault diagnosis methods. By continuously tracking the …

The fault diagnosis of analog circuits has made many ways, such as the fault dictionary
method, device parameter identification method and so on. However, due to the diversity of …

This paper presents a new fault diagnosis method for sensors in an air-handling unit based
on neural network pre-processed by wavelet and fractal (NNPWF). Three-level wavelet …

To improve the limitation of applying traditional fault diagnosis method to the diagnosis of
multi-concurrent vibrant faults of aeroengine, a new diagnosis approach combining the …
