VisSim/ModelWizard 
 VisSim/ModelWizard
is a Windows®-based software program for developing 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.
The product 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 specified by the user. 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.
 With VisSim/ModelWizard,
generating models is simple. The wizard interface 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.
Used in conjunction with VisSim/OptimizePRO™,
a VisSim product option, VisSim/ModelWizard
lets you automatically calculate optimal PID controller gains relative
to user-defined parameters such as rise-time, settling-time, overshoot
and steady-state error.
