A tuning method for first-order processes with PI controllers.

Author(s) : BEKKER J. E., MECKL P. H., HITTLE D. C.

Summary

The paper looks at the development of a tuning method for use with the PI controllers that are being used to control first-order heating, ventilating, and air-conditioning (HVAC) processes. The tuning method is developed in two stages; the first stage applies to fast-acting actuators, while the second stage is specific to the electric actuators found in many HVAC systems. The tuning method was tested experimentally on a humidification control system. Experiments showed that the tuning method was capable of producing smooth, quick, critically damped responses with a time-delayed, first-order process that included a constant-velocity actuator.
