About Operating Points in Control System Tuner
When you use Control System Tuner with a Simulink model, the software computes
system responses and tunes controller parameters for a linearization of the model. That
linearization can depend on model operating conditions.By default, Control System Tuner linearizes at the operating point specified in the model,
which comprises the initial state values in the model (the model initial conditions). You
can specify one or more alternate operating points for tuning the model. Control System
Tuner lets you compute two types of alternate operating points:- Simulation snapshot time. Control System Tuner simulates the model for the amount
of time you specify, and linearizes using the state values at that time. Simulation
snapshot linearization is useful, for instance, when you know your model reaches an
equilibrium state after a certain simulation time. - Steady-state operating point. Control System Tuner finds a steady-state operating
point at which some specified condition is met (trimming). For example, if your model
represents an automobile motor, you can compute an operating point at which the
motor operates steadily at 2000 rpm.
For more information on finding steady-state operating points, see “About Operating
Points” on page 1-3 and “Compute Steady-State Operating Points” on page 1-6.Linearize at Simulation Snapshot Times
This example shows how to compute linearizations at one or more simulation snapshot
times.In the Control System tab, in the Operating Point menu, select Linearize At.Specify Operating Points for Tuning in Control System Tuner
