A level control system is provided. The system includes multiple sensors configured to measure multiple parameters related to a drum, wherein the multiple parameters include a drum liquid level, a vapor flow rate leaving the drum, a downstream pressure of the drum, and a feed-liquid flow rate entering the drum. The system also includes a level controller configured to adjust a level control valve in accordance with a signal representative of the drum liquid level, a signal representative of the downstream pressure and a signal representative of a given drum liquid level set point. The level controller is further configured to receive a feedback signal representative of a combination of a fraction of the signal representative of the drum liquid level and a fraction of the signal representative of the downstream pressure.
