    Abstract: Systems and methods for estimating a flow rate through a device are provided. One or more pressure sensors measure a plurality of pressure differentials across a tested device. A temporary flow rate sensor measures a plurality of flow rates through the tested device. Each of the measured flow rates corresponds to one of the measured pressure differentials. A regression model trainer generates regression coefficients for a flow rate model using the measured pressure differentials and corresponding flow rates. A flow rate estimator uses the flow rate model to estimate a flow rate through a tested or untested device as a function of a measured pressure differential across the tested or untested device.

    Abstract: A fault parameter of an energy consumption model is modulated. The energy consumption model is used to estimate an amount of energy consumption at various values of the fault parameter. A first set of variables is generated including differences between a target value of the fault parameter and the various values of the fault parameter. A second set of variables is generated including differences between an estimated amount of energy consumption with the fault parameter at the target value and the estimated amounts of energy consumption with the fault parameter at the various values. The first set of variables and second set of variables are used to develop a regression model for the fault parameter. The regression model estimates a change in energy consumption based on a change in the fault parameter. Regression models are developed for multiple fault parameters and used to prioritize faults.

    Abstract: A system for controlling a flow rate of a fluid through a valve is provided. The system includes a valve and an actuator. The actuator includes a motor and a drive device that is coupled to the valve for driving the valve between multiple positions. The system further includes a flow rate sensor and a controller that is communicably coupled with the flow rate sensor and the motor. The controller is 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 a flow rate measurement, and receive a second flow rate setpoint. In response to a determination that certain low flow criteria are satisfied, the controller is configured to determine a second actuator position setpoint using the proportional variable deadband control technique based on a low flow compensation setpoint.

    Abstract: A pressure disturbance rejection valve assembly is provided. The valve assembly includes a valve, a flow rate sensor, and an actuator. The actuator includes a motor, a drive device configured to be driven by the motor and coupled to the valve for driving the valve within a range of positions, and a position sensor configured to measure a rotational position of the drive device. The actuator further includes a communications mechanism configured to receive a flow rate setpoint and a processing circuit. The processing circuit is configured to determine an actuator position setpoint using a feedback control mechanism based on the flow rate setpoint and the flow rate measurement, operate the motor to drive the drive device to the actuator position setpoint, detect a fault condition based at least in part on the rotational position measurement or the flow rate measurement, and perform a fault mitigation action in response to detection of the fault condition.

    Abstract: A system for controlling a flow rate of a fluid through a valve is provided. The system includes a valve and an actuator. An actuator drive device is driven by an actuator motor and is coupled to the valve for driving the valve between multiple positions. The system further includes 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. The controller is configured to receive a flow rate measurement from the flow rate sensor, adjust a control deadband based on an actuator command history, and determine a compensated position setpoint using the flow rate measurement, the adjusted control deadband, and a proportional variable deadband control technique. The controller is further configured to operate the motor to drive the drive device to the compensated actuator position setpoint.

    Abstract: An actuator of an environmental control system of a building including a motor and a drive device driven by the motor and configured to drive a valve within a range of positions. The actuator includes one or more printed circuit boards including one or more processing circuits configured to obtain a raw measurement data set from transducers and generate a flow signal based on the raw measurement data set. The flow signal indicates a flow rate of a fluid through a conduit. The one or more processing circuits are configured to determine an actuator position setpoint based on a flow rate setpoint and the flow signal and operate the motor to drive the drive device to the actuator position setpoint. The motor, the drive device, and the one or more printed circuit boards are located within a common device chassis.

    Abstract: A system for controlling a flow rate of a fluid through a valve includes a controller. The controller is configured to receive a raw flow rate measurement from a flow rate sensor assembly configured to measure the flow rate. The controller is further configured to apply a flow rate measurement filter to the raw flow rate measurement to generate a filtered flow rate measurement. The controller is further configured to control actuation of an actuator configured to change the flow rate using the filtered flow rate measurement. The controller is configured to automatically adjust the flow rate measurement filter in response to detecting an event that causes stoppage of the actuation of the actuator.
