DOI: 10.1016/j.applthermaleng.2019.114098

Abstract: Abstracts Sensors play essential roles in industrial automatic control systems. The faulty or inaccurate sensors may cause uncomfortable thermal environments, shortened component lifetime and energy consumption loss. Considering the condition-adaptive issue of principal component analysis… read more here.

DOI: 10.1016/j.asr.2019.02.007

Abstract: Abstract Satellite attitude determination accuracy significantly drops when sensor-fault occurs. Hence, a proper mitigation strategy to detect sensor-fault and accurately estimate corresponding fault magnitudes is mandatory for robust and accurate attitude determination. In this paper,… read more here.

DOI: 10.1016/j.enbuild.2018.05.025

Abstract: Abstract Since the outdoor and indoor load conditions always change continuously, it may lead to the various operation characteristics in chillers. If a single principal component analysis (PCA) model is applied to detect and diagnose… read more here.
