A temperature controller for VAV air-handling units based on simplified physical models.

Type of article: Article

Summary

A feedforward controller based on simplified physical models is described for air-handling units to supplement conventional PI control. Inverse static models of the controlled processes produce feedforward control action and the PI feedback loop compensates for modeling errors and unmeasured disturbances. This paper describes the control scheme and models, and presents results from tests carried out using a simulated air-handling unit.
