Abstract
A decentralized control system with adjustable operations includes control devices for arrangement at a system for undertaking. When so arranged, the control devices determine a measurement of a control parameter at a respective one of the control devices, and electronically share the measurement with other one or ones of the control devices such that each of the control devices receive measurements from a different one or combination of the control devices. Upon receipt of an out-of-tolerance measurement from any other of the control devices, the respective one of the control devices adjusts its operational setpoint and/or sends a signal to a same and/or different other one or ones of the control devices to adjust their operational setpoint.
Claims21
A decentralized control system with adjustable operations, said decentralized control system comprising:
- control devices for arrangement at a system for undertaking operations, and when so arranged, configured to:
- determine a measurement of a control parameter at a respective one of the control devices;
- electronically share the measurement with other one or ones of the control devices such that each of the control devices receive measurements from a different one or combination of the control devices;
- and
- upon receipt of an out-of-tolerance measurement from any other of the control devices at the respective one of the control devices, adjust an operational setpoint of said respective one of the control devices and/or send a signal to a same and/or different other one or ones of the control devices to adjust the operational setpoint of such one or ones of the control devices.
A decentralized control system with adjustable operations, said decentralized control system comprising:
- control devices arranged sequentially at a system undertaking operations, each comprising a sensor and an energy application element, wherein each of the control devices is configured to:
- determine a measurement of a control parameter at a respective one of the control devices based, at least in part, on data received from the sensor of the respective one of the control devices;
- apply a particular level of energy or refrain from applying the energy to the system by way of the energy application element of the respective one of the control devices based, at least on part, on the measurement relative to an operational setpoint of the respective one of the control devices;
- electronically transmit the measurement to at least two other ones of the control devices in the sequential arrangement such that each of the control devices receive measurements of the control parameter from a different combination of the control devices;
- and
- upon receipt of an out-of-tolerance measurement from any other of the control devices at the respective one of the control devices, adjust the operational setpoint of said respective one of the control devices and/or send a signal to a same and/or different other one or ones of the control devices to adjust the operational setpoint of such one or ones of the control devices.
A method of providing decentralized control and adjustable operations for a system, said method comprising:
- determining a measurement of a control parameter at a respective one of a plurality of control devices arranged sequentially at a system undertaking operations, where each of the control devices comprises a sensor and an energy application element, where the measurement is determined based, at least in part, on data received from the sensor of the respective one of the control devices;
- applying a particular level of energy or refraining from applying the energy to the system by way of the energy application element of the respective one of the control devices based, at least on part, on the measurement relative to an operational setpoint of the respective one of the control devices;
- electronically transmitting the measurement to other one or ones of the control devices in the sequential arrangement such that each of the control devices receive measurements of the control parameter from a different one or combination of the control devices;
- and
- receiving of an out-of-tolerance measurement from a same or different other one the control devices at the respective one of the control devices, and in response, perform one or both of:
- adjusting the operational setpoint of said respective one of the control devices;
- and
- electronically transmitting a signal to a same and/or different other one or ones of the control devices to adjust the operational setpoint of such one or ones of the control devices.
