Abstract: A cascaded control system configured to modify an environmental condition of a building includes a valve configured to regulate a flow of a fluid through a conduit, an actuator including a motor and a drive device, and a communications mechanism. The communications mechanism is configured to receive a flow rate setpoint from an external control device of an outer control loop. The cascaded control system further includes a processing circuit coupled to the motor and the communications mechanism. The processing circuit is configured to determine an actuator position setpoint using a cascaded feedback control mechanism based on the flow rate setpoint and a flow rate measurement from a flow rate sensor of an inner control loop and to operate the motor to drive the drive device to the actuator position setpoint.

Abstract: A system for generating and using a predictive model to control building equipment includes building equipment operable to affect one or more variables in a building and an operating data aggregator that collects a set of operating data for the building equipment. The system includes an autocorrelation corrector that removes an autocorrelated model error from the set of operating data by determining a residual error representing a difference between an actual output of the building equipment and an output predicted by the predictive model, using the residual error to calculate an autocorrelation for the model error, and transforming the set of operating data using the autocorrelation. The system includes a model generator module that generates a set of model coefficients for the predictive model using the transformed set of operating data and a controller that controls the building equipment by executing a model-based control strategy that uses the predictive model.

Abstract: An electrical energy storage system includes a battery configured to store and discharge electric power to an energy grid, a power inverter configured to use battery power setpoints to control an amount of the electric power stored or discharged from the battery, and a controller. The controller is configured to generate optimal values for the battery power setpoints as a function of both an estimated amount of battery degradation and an estimated amount of frequency response revenue that will result from the battery power setpoints.

Abstract: A building control system includes a hybrid controller which receives measurements from sensors and provides control signals to building equipment. The hybrid controller includes a state transition controller, a state history tracker, and an adaptive user interface generator. The state transition controller transitions between multiple discrete operating states by executing state transitions. The state history tracker records a state history including a sequence of state transitions executed by the state transition controller and/or a sequence of operating states resulting from the state transitions. The adaptive user interface generator generates an adaptive user interface including a representation of the multiple discrete operating states and the state transitions therebetween. The adaptive user interface includes state history controls operable to navigate the state history and select an operating state defined by the state history. The adaptive user interface generator automatically updates the adaptive user interface to provide information about the selected operating state.

Abstract: A photovoltaic energy system includes a photovoltaic field configured to convert solar energy into electrical energy, cloud detectors configured to detect a cloud approaching the photovoltaic field, and a controller. The controller uses the cloud detectors to predict a disturbance in the electric power output of the photovoltaic energy system. The controller determines a time at which the disturbance is expected to occur and determines an amount by which the electric power output is expected to decrease. The controller can preemptively adjust the electric power output of the photovoltaic energy system in accordance with a predetermined ramp rate.
