    • Automatic Commissioning of Multiple VAV Terminals 
      Qin, J.; Wang, S. (Energy Systems Laboratory (http://esl.tamu.edu); Texas A&M University (http://www.tamu.edu), 2004)
      A site survey on a modern operating commercial building screened 261 ineffective VAV (Variable Air Volume) boxes (20.9% of the total boxes in the building) and summarized ten typical faults for VAV air-conditioning system(s) ...
    • Diagnosis and Isolation of Air Gap Eccentricities in Closed-loop Controlled Doubly-Fed Induction Generators 
      Meenakshi Sundaram, Vivek (2012-07-16)
      With the widespread use of doubly-fed induction generators (DFIG) in wind energy conversion systems, condition monitoring is being given importance. Non-intrusive techniques like motor current signature analysis (MCSA), ...
    • Health Monitoring and Continuous Commissioning of Centrifugal Chiller Systems 
      Cui, J.; Wang, S. (Energy Systems Laboratory (http://esl.tamu.edu); Texas A&M University (http://www.tamu.edu), 2004)
      This paper presents strategies for detecting and diagnosing the chiller component faults and the sensor faults involved in chiller conditioning monitoring and control. The two strategies are used in series. One strategy diagnoses ...
    • Low-cost motor drive embedded fault diagnosis systems 
      Akin, Bilal (2009-05-15)
      Electric motors are used widely in industrial manufacturing plants. Bearing faults, insulation faults, and rotor faults are the major causes of electric motor failures. Based on the line current analysis, this dissertation ...
    • Optimization of Fault Detection/Diagnosis Model for Thermal Storage System Using AIC 
      Pan, S.; Zheng, M.; Nakahara, N. (Energy Systems Laboratory (http://esl.tamu.edu); Texas A&M University (http://www.tamu.edu), 2006)
      The authors simulated the human ability of pattern recognition mathematically, through finding the state-change characteristics of the objective system from actual measurements using statistical analytical tech-niques. The ...
    • Research on Fault Detection and Diagnosis of Scrolling Chiller with ANN 
      Zhou, Y.; Zheng, J.; Liu, Z.; Yang, C.; Peng, P. (Energy Systems Laboratory (http://esl.tamu.edu); Texas A&M University (http://www.tamu.edu), 2006)
      At first the basic research about FDD is summarized, and a detection model based on ANN is initially set up. The paper presents experiments that simulate seven faults, including change flow rate of chilled water, cooling ...
    • Robust Condition Monitoring and Fault Diagnosis of Variable Speed Induction Motor Drives 
      Choi, Seungdeog (2012-02-14)
      The main types of faults studied in the literature are commonly categorized as electrical faults and mechanical faults. In addition to well known faults, the performance of a diagnostic algorithm and its operational ...
