An integrated robust strategy for diagnosing sensor faults in building chilling systems.

Author(s) : WANG J. B., WANG S., BURNETT J.

Type of article: Article

Summary

The integrated strategy, which extends the works of Wang and Wang (1999), is based on the universal conservation relationships for mass and energy. Biases in temperature sensors and flow meters are estimated by minimizing the sums of the squares of the mass and energy balance residuals. A robust approach using a genetic algorithm is used to systematically minimize the sums of the squares of the associated heat balance residuals so that the biases are estimated more reliably and accurately.
