A system for controlling a flow rate of a fluid through a valve , the system comprising: - a valve configured to regulate a flow of fluid through a conduit ; - an actuator comprising a motor and a drive device , the drive device driven by the motor and coupled to the valve for driving the valve between multiple positions; - a flow rate sensor configured to measure the flow rate of the fluid through the valve ; and - a controller that is communicably coupled with the flow rate sensor and the motor , the controller configured to: - receive a first flow rate setpoint; - determine a first actuator position setpoint using a proportional variable deadband control technique based on the first flow rate setpoint and at least one flow rate measurement from the flow rate sensor ; - operate the motor to drive the drive device to the first actuator position setpoint; - receive a second flow rate setpoint; and - in response to a determination that each of a plurality of low flow criteria are satisfied, determine a second actuator position setpoint using the proportional variable deadband control technique based on a low flow compensation setpoint and at least one flow rate measurement from the flow rate sensor , wherein the low flow compensation setpoint causes the controller to set the second actuator position to a value corresponding to a fully closed position of the valve using the proportional variable deadband control technique; and - operate the motor to drive the drive device to the second actuator position setpoint. - a valve configured to regulate a flow of fluid through a conduit ; - an actuator comprising a motor and a drive device , the drive device driven by the motor and coupled to the valve for driving the valve between multiple positions; - a flow rate sensor configured to measure the flow rate of the fluid through the valve ; and - a controller that is communicably coupled with the flow rate sensor and the motor , the controller configured to: - receive a first flow rate setpoint; - determine a first actuator position setpoint using a proportional variable deadband control technique based on the first flow rate setpoint and at least one flow rate measurement from the flow rate sensor ; - operate the motor to drive the drive device to the first actuator position setpoint; - receive a second flow rate setpoint; and - in response to a determination that each of a plurality of low flow criteria are satisfied, determine a second actuator position setpoint using the proportional variable deadband control technique based on a low flow compensation setpoint and at least one flow rate measurement from the flow rate sensor , wherein the low flow compensation setpoint causes the controller to set the second actuator position to a value corresponding to a fully closed position of the valve using the proportional variable deadband control technique; and - receive a first flow rate setpoint; - determine a first actuator position setpoint using a proportional variable deadband control technique based on the first flow rate setpoint and at least one flow rate measurement from the flow rate sensor ; - operate the motor to drive the drive device to the first actuator position setpoint; - receive a second flow rate setpoint; and - in response to a determination that each of a plurality of low flow criteria are satisfied, determine a second actuator position setpoint using the proportional variable deadband control technique based on a low flow compensation setpoint and at least one flow rate measurement from the flow rate sensor , wherein the low flow compensation setpoint causes the controller to set the second actuator position to a value corresponding to a fully closed position of the valve using the proportional variable deadband control technique; and - operate the motor to drive the drive device to the second actuator position setpoint. <EOS>
