| VisSim/ModelWizard
allows you to develop high-fidelity, dynamic models of process plant
subsystems or components from real-time plant and historic data.
Using VisSim/ModelWizard, process control engineers and technicians
can easily create models for tuning controllers without spending
days or weeks developing the models.
VisSim/ModelWizard consists of a simple
wizard interface combined with a set of sophisticated algorithms.
The underlying algorithms identify the key frequencies of a system
-- even in the presence of noise -- and generate a mathematical
model of optimal order, or alternatively, of an order that you
specified. The software is designed to produce models for single
input/single output (SISO) systems and is particularly well-suited
for PID controlled systems. These models can be easily configured
with other VisSim blocks (for example, PID control blocks) to
perform process simulation, off-line tuning (optimization) or
operator training.
VisSim/ModelWizard guides
you through an easy four step process,
then automatically produces a VisSim transfer function block that
represents the system. You can then
connect pre-configured VisSim PI, PD or PID blocks to the transfer
function block to create, simulate, and
tune the control system.
In fact with
the optional add-on
VisSim/OptimizePRO,
you can automatically calculate optimal
PID controller gains relative to user-defined parameters such as
rise-time, settling-time, overshoot, and
steady-state error.

VisSim/ModelWizard is a
very easy to use tool. We have successfully used it in conjunction
with VisSim/Real-TimePRO to reduce machine downtime caused by poor
controller performance. Using VisSim/ModelWizard we have reduced the
number of site visits required to solve the control problem from two
or more site visits to just one. Furthermore, we have reduced
machine downtime significantly and now spend only three days to
identify and correct the problem as opposed to the 10 to 15 working
days required before using VisSim/ModelWizard.
