Emulation is defined as an intermediate stage of simulation where the model
represents the "as specified" mechanical plant and equipment, but not the control logic
required to drive it. This thesis investigates the utility of providing a computer representation
of the functional elements to be controlled by system control programs. These
representations or "emulatorsu mimic the behavior of the system, or factory being controlled.
The advantages of such a scheme are that developers of control software, are able to test
out new control methodologies withoit actually connecting to the hardware system under
control.
This thesis investigates system control for automated manufacturing systems and
identifies how emulation can be used as a valid tool in reducing the implementation time of
such systems. The functions and characteristics of system control are identified as well as
the problems associated with their implementation. The problems are then categorized to
identify where emulation is a valid tool for problem resolution. This thesis is concluded by a
description of a software demonstration which validated the concept of using emulation to
solve system control problems.
