Online reduction of chattering alarms due to random noise and oscillation ⋆
نویسندگان
چکیده
Chattering alarms repeatedly make transitions between alarm and non-alarm states without response from operators, and severely deteriorate the performance of industrial alarm systems. Two rules are formulated based on the metrics of alarm durations and intervals to detect chattering alarms caused by random noise and oscillation. An online method is proposed to reduce the number of the chattering alarms via delay timers. Industrial examples are provided to illustrate the effectiveness of the formulated rules and the proposed method.

An online method to remove chattering and repeating alarms based on alarm durations and intervals
Chattering and repeating alarms, which repeatedly make transitions between alarm and non-alarm states without operators’ response, are the most common form of nuisance alarms encountered in industrial plants. The paper formulates two novel rules to detect chattering alarms caused by random noise and repeating alarms by regular patterns such as oscillation, and proposes an online method to effec...
متن کاملAn online method for detection and reduction of chattering alarms due to oscillation
Chattering alarms, which repeatedly and rapidly make transitions between alarm and normal states in a short time period, are the most common form of nuisance alarms that severely degrade the performance of alarm systems for industrial plants. One reason for chattering alarms is the presence of oscillation in process signals. The paper proposes an online method to promptly detect the chattering ...
متن کاملUsing a novel method for random noise reduction of seismic records
Random or incoherent noise is an important type of seismic noise, which can seriously affect the quality of the data. Therefore, decreasing the level of this category of noises is necessary for increasing the signal-to-noise ratio (SNR) of seismic records. Random noises and other events overlap each other in time domain, which makes it difficult to attenuate them from seismic records. In this r...

An asymptotically stable direct adaptive fuzzy PI sliding modecontroller is proposed for a class of nonlinear uncertain systems. In contrast toother existing approaches of handling disturbances, the proposed approachdoes not require this bound to be known, only requiring that it exists.Moreover, a PI control structure is used to attenuate chattering. The approachis applied to stabilize an open-...
متن کاملActive Noise Cancellation using Online Wavelet Based Control System: Numerical and Experimental Study
Reaction wheels (RWs) used for attitude control of space vehicle systems usually encounter with undesired wide band noises. These noises which significantly affect the performance of regulator controller must tune the review or review rate of RWs. According to wide frequency band of noises in RWs the common approaches of noise cancellation cannot conveniently reduce the effects of the noise. Th...
