摘要： A system for controlling an operation of an air-conditioning system including a heat exchanger is provided. The system comprises a processor that executes a neural network trained to simulate an operation of the heat exchanger for a test control input, to produce an output of the simulation based on historical data defining a state of the heat exchanger. The historical data includes a sequence of historical control inputs provided to the heat exchanger and a sequence of historical outputs of the operation of the heat exchanger corresponding to the sequence of historical control inputs. The processor determines a control command to the air-conditioning system based on the predicted test output of the simulation of the operation of the heat exchanger for the test control input and transmits the determined control command to an actuator of the air-conditioning system.

摘要： A system for controlling or optimizing the performance of a vapor compression system by modifying the actuator commands via an output interface, that realizes thermofluid property functions and their derivatives as spline functions which are represented in a coordinate system that is aligned with a fluid saturation curve. The system includes an interface configured to receive measurement data from sensors, a memory configured to store thermofluid property data and computer-executable programs including a B-spline method, and a processor for performing the computer-implemented method. The processor is configured to take as input two thermofluid property variables, and compute a coordinate transformation in which one axis of the coordinates is aligned with the liquid and vapor saturation curves. In the saturation-curve aligned coordinates, a spline function represents the thermofluid property function, with coefficients and knots stored in memory. The spline function is constructed in a manner such that derivatives of the thermofluid property function may be discontinuous across the saturation curve.

摘要： A branch controller operates with a system for temperature and humidity control. The branch controller includes a fluid control system for controlling a flow of the liquid desiccant in an arrangement of channels forming a first path for exchanging the liquid desiccant between a liquid desiccant conditioning unit and at least a first space conditioning unit and a second path for directing the liquid desiccant received from the first space conditioning unit to a second space conditioning unit. The branch controller includes a processor for comparing operational conditions of the first space conditioning unit and the second space conditioning unit. The processor selects between the first path and the second path based on the comparison and commands the fluid control system to control the flow of the liquid desiccant according to the selected path.

摘要： A controller and a method for optimizing a controlled operation of a system performing a task is provided. The method for optimizing the controlled operation of the system comprises accessing a probabilistic distribution of a performance function trained to provide a relationship between different combinations of control parameters for controlling the system and their corresponding costs of operation, selecting a combination of control parameters from the different combinations of control parameters, such that the selected combination of control parameters is having the largest likelihood of being optimal at the probabilistic distribution of the performance function. The method further comprises controlling the system using the selected combination of the control parameters and modifying the probabilistic distribution of the performance function conditioned on the selected combination of the control parameters and the corresponding cost of operation.

摘要： A system and a method for calibrating a model of thermal dynamics of thermal state in an environment of a building conditioned by an operation of a heating, ventilating, and air-conditioning (HVAC) system is provided. The method includes receiving values of the control inputs to the actuators of the HVAC system and values of the thermal state at locations of the environment caused by the operation of the HVAC system according to the values of the control inputs, and computing a probabilistic surrogate model iteratively, using a Bayesian optimization, until a termination condition is met. The method further comprises outputting, when the termination condition is met, an optimal combination of the different parameters of the model of thermal dynamics having the largest likelihood of being a global minimum at the probabilistic surrogate model according to an acquisition function of the first two order moments of the calibration errors.

摘要： A method for controlling an operation of a vapor compression system (VCS) determines values of measured outputs of the operation of the VCS that include performance and constrained outputs. The method determines states of the VCS using an estimator model of the VCS defining a relationship between the states of the VCS, control inputs and controlled outputs, such that a difference between outputs predicted using the estimator model and the measured outputs asymptotically approaches zero. The states of the VCS include a main state representing the operation of the VCS and an auxiliary state representing the effect of unknown disturbances on each measured output of the VCS. The control inputs for controlling the operation of the VCS are determined using a prediction model, such that the constrained output satisfies the constraints, and a difference between the performance output and the value of the setpoint asymptotically approaches zero.

摘要： A method controls a vapor compression system including a variable speed compressor. A desired discharge temperature of the compressor is determined using a mapping between values of the discharge temperature of the compressor and values of speed of the compressor and outdoor air temperature. A transition function for transitioning a current discharge temperature to the desired discharge temperature is determined, such that the transition function is continuous and a rate of change of the transition function is limited. Next, a valve of the vapor compression system is controlled such that the discharge temperature is transitioned to the desired discharge temperature based on the transition function.
