Systems and methods for controlling drum levels using flow

A system comprising:

• a controller configured to operatively couple to an industrial system having a drum, wherein the controller comprises a processor, wherein the processor is configured to:
• determine a commanded fluid flow rate of the drum of the industrial system, wherein the commanded fluid flow rate comprises a rate of fluid entering the drum of the industrial system, exiting the drum of the industrial system, or a combination thereof, and wherein the rate of fluid comprises a volume of fluid per unit of time;
• determine a measured flow rate change of the fluid, wherein the measured flow rate change comprises a measured change in volume of fluid per unit of time, and wherein the measured flow rate change is a measured value resulting from the rate of fluid comprising the volume of fluid per unit of time entering or exiting of the drum of the industrial system as controlled via the commanded fluid flow rate;
• determine a variable multiplier based at least in part on the commanded fluid flow rate and the measured flow rate change;
• and
• derive a multiplied flow rate command for the industrial system by applying the variable multiplier to the commanded fluid flow rate, wherein the processor is configured to transmit a signal to the industrial system to control the rate of fluid entering the drum of the industrial system, exiting the drum of the industrial system, or the combination thereof, based at least in part on the multiplied flow rate command, and wherein the signal is configured to actuate an actuator to maintain the drum at a constant fluid level.

One or more tangible, non-transitory, machine-readable media comprising instructions configured to cause a processor to:

• determine a commanded fluid flow rate of a drum of an industrial system, wherein the commanded fluid flow rate comprises a rate of fluid entering the drum of the industrial system, exiting the drum of the industrial system, or a combination thereof, and wherein the rate of fluid comprises a volume of fluid per unit of time;
• determine a measured flow rate change of the fluid, wherein the measured flow rate change comprises a measured change in volume of fluid per unit of time, and wherein the measured flow rate change is a measured value resulting from the rate of fluid comprising the volume of fluid per unit of time entering or exiting of the drum of the industrial system as controlled via the commanded fluid flow rate;
• determine a variable multiplier based at least in part on the commanded fluid flow rate and the measured flow rate change;
• derive a multiplied flow rate command for the industrial system by applying the variable multiplier to the commanded fluid flow rate;
• and
• transmit a signal to the industrial system to control the rate of fluid entering the drum of the industrial system, exiting the drum of the industrial system, or the combination thereof, based at least in part on the multiplied flow rate command, wherein the signal is configured to actuate an actuator to maintain the drum at a constant fluid level.
