CASCADE CONTROL SYSTEMS AND DEHUMIDIFIER SYSTEMS FOR CONTROLLING A HUMIDITY LEVEL

원문 (중국어)

A cascade control system of a dehumidifier for controlling a humidity level including: a heater for adjusting the humidity level of the outlet process air by heating inlet reactivation air, a primary control module for controlling the humidity level by controlling the dehumidifier, and a secondary control module for controlling the temperature of inlet reactivation air to match a desired temperature setpoint by controlling the heater. The primary control module is configured to regulate the humidity level to match a desired humidity setpoint while providing the desired temperature setpoint for the secondary control module as output. The primary controller is a Model Predictive Control, MPC, module configured to predict future humidity levels and to calculate the desired temperature setpoint for the secondary control module based on the predicted humidity levels.
