An On-line Self-tuning Algorithm of PI Controller for the Heating and Cooling Coil in Buildings
Abstract
An on-line self-tuning algorithm of PI controller
for the heating and cooling coil in buildings is
described in the paper. The algorithm evaluates
the controller performance by the integral
square error (ISE) of the coil supply air
temperature, and identifies the corrections of the
P and I gains by observing the spectrum
distribution of the ISE. This method is easy to
implement in the HVAC energy control systems
due to its simplicity. This paper describes the
basic feature of the on-line self-tuning algorithm
for typical PI controllers in the energy
management system and presents the detail of
the algorithm. Demonstration example are
presented as well.
