Abstract
A system may include virtual sensors representative of operation of different portions of a tangible system. The virtual sensors may receive measured characteristics of the tangible system and may separately output values representative of operation of a common component of the tangible system based on the one or more measured characteristics input into each virtual sensor. A controller may receive the output values from the virtual sensors and determine a state of the common component by comparing the first output value with the second output value.
Claims17
A method, comprising:
- obtaining first and second mathematical models representative of operations of respective first and second portions of a tangible system, each of the first mathematical model and the second mathematical model configured to output a respective first or second output value representative of operation of a common component of the tangible system that is included in both the first and second portions of the tangible system, wherein a variable of the first mathematical model is independent from a variable of the second mathematical model;
- inputting at least a first input value of at least a first measured characteristic of the first portion of the tangible system into the first mathematical model and at least a second input value of a second measured characteristic of the second portion of the tangible system into the second mathematical model;
- obtaining the first output value from the first mathematical model based on the at least the first input value and the second output value from the second mathematical model based on the at least the second input value;
- determining a state of the common component by comparing the first output value from the first mathematical model with the second output value from the second mathematical model;
- and
- changing operation of the common component based on the state of the common component that is determined.
A system, comprising:
- a first virtual sensor representative of operation of a first portion of a tangible system, the first virtual sensor configured to receive one or more first measured characteristics of the tangible system and to output a first output value representative of operation of a common component of the tangible system based on the one or more first measured characteristics;
- a second virtual sensor representative of operation of a second portion of the tangible system, the second virtual sensor configured to receive one or more second measured characteristics of the tangible system and to output a second output value representative of operation of the common component of the tangible system based on the one or more second measured characteristics, the common component of the tangible system included in both the first and second portions of the tangible system;
- and
- a controller configured to receive the first output value from the first virtual sensor and the second output value from the second virtual sensor, the controller configured to determine a state of the common component by comparing the first output value with the second output value,
- wherein the first virtual sensor represents a first mathematical model of operation of the first portion of the tangible system, the second virtual sensor represents a second mathematical model of operation of the second portion of the tangible system, and a variable of the first mathematical model is independent from a variable of the second mathematical model, and
- wherein the controller is further configured to change operation of the common component based on the state of the common component that is determined.
