Fixed-point virtual sensor control system and method
First Claim
1. A computer system for converting a virtual sensor model to fixed-point representation used by a control system of a machine, comprising:
- a database configured to store information relevant to the virtual sensor model; and
a processor configured to;
establish the virtual sensor model indicative of interrelationships between at least one sensing parameter and a plurality of measured parameters related to the machine;
obtain data and function information representing the virtual sensor model;
convert the data information into fixed-point representation;
convert the function information into fixed-point representation; and
load the converted fixed-point representation of data information and function information in the control system such that the control system uses the virtual sensor model in fixed-point arithmetic operation to control the machine.

Abstract
One aspect of the present disclosure includes a method for a control system of a machine. The method may include establishing a virtual sensor model indicative of interrelationships between at least one sensing parameter and a plurality of measured parameters related to the machine. The method may also include obtaining data and function information representing the virtual sensor model and converting the data information into fixed-point representation. Further, the method may include converting the function information into fixed-point representation and loading the converted fixed-point representation of data information and function information in the control system such that the control system uses the virtual sensor model in fixed-point arithmetic operation.
