| 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.
