Abstract
A method and system for co-ordinating control of a plurality of sensorless devices. Each device includes a communication subsystem and configured to self-detect one or more device properties, the device properties resulting in output having one or more output properties. The method includes: detecting inputs including the one or more device properties of each device, correlating, for each device, the detected one or more device properties to the one or more output properties, and co-ordinating control of each of the devices to operate at least one of their respective device properties to co-ordinate one or more output properties for the combined output to achieve a setpoint. In some example embodiments, the setpoint can be fixed, calculated or externally determined.
Claims25
A control system, comprising:
- two or more devices each having a respective internal sensor and each having a respective operable element, each device having a communication subsystem and configured to self-detect one or more device properties of the operable element, the device properties resulting in output having one or more output properties;
- at least one memory which stores, for each device, correlation data between the one or more device properties and the one or more output properties for that device;
- and
- one or more controllers configured to:
- detect the one or more device properties self-detected by each device from the respective internal sensor,
- determine a speed variable of each device,
- correlate, for each device, based on the stored correlation data, the speed variable and the detected one or more device properties, to the one or more output properties for that device,
- determine, for each device, a value of the one or more output properties for that device which result in combined output of the devices achieving an output setpoint, and
- co-ordinate control of each device to operate their respective one or more device properties, based on the stored correlation data, their respective determined value of the one or more output properties for that device.
A method for co-ordinating control of two or more devices each having a respective internal sensor and each having a respective operable element, each device having a communication subsystem and configured to self-detect one or more device properties of the operable element, the device properties resulting in output having one or more output properties, wherein the one or more device properties, wherein at least one memory stores, for each device, correlation data between the one or more device properties and the one or more output properties for that device, the method comprising:
- detecting the one or more device properties self-detected by each device from the respective internal sensor;
- determine a speed variable of each device;
- correlating, for each device, based on the stored correlation data, the speed variable and the detected one or more device properties, to the one or more output properties for that device;
- determining, for each device, a value of the one or more output properties for that device which result in combined output of the devices achieving an output setpoint;
- and
- co-ordinating control of each device to operate their respective one or more device properties, based on the stored correlation data, their respective determined value of one or more output properties for that device.
A non-transitory computer readable medium having instructions stored thereon executable by one or more processors for co-ordinating control of two or more circulating devices each having a respective internal sensor and each having a respective operable element, each device having a communication subsystem and configured to self-detect one or more device properties of the operable element, the device properties resulting in output having one or more output properties, wherein the one or more device properties, wherein at least one memory stores correlation data between the one or more device properties and the one or more output properties for that device, the instructions comprising:
- instructions for detecting the one or more device properties self-detected by each device from the respective internal sensor;
- instructions for determining a speed variable of each device;
- instructions for correlating, for each device, based on the stored correlation data, the speed variable and the detected one or more device properties, to the one or more output properties for that device;
- instructions for determining, for each device, a value of the one or more output properties for that device which result in combined output of the devices achieving an output setpoint;
- and
- instructions for co-ordinating control of each device to operate their respective one or more device properties to achieve, based on the stored correlation data, their respective determined value of the one or more output properties for that device.
