SYSTEM AND METHOD FOR DRUM LEVEL CONTROL WITH TRANSIENT COMPENSATION

A level control system for controlling the liquid level in a boiler drum is provided. The level control system uses an integration parameter when operating in a non-transient condition to provide a control signal into a flow control loop controlling a level control valve for the liquid level in the boiler drum. When a transient condition is identified by a predictive controller, the integration parameter is interrupted and a gain vector is generated to modify the control constants and optionally modify feedforward to adjust control signal into the flow control loop during transient operation of the level control valve.
