**Package: **sdo

Set up steady-state operating point computation

`OpPointSetup = sdo.OperatingPointSetup(opSpec,inputsToUse,statesToUse)`

OpPointSetup = sdo.OperatingPointSetup(___,[findopOpts])

An *operating point* of a dynamic system defines the
states and root-level input signals of the model at a specific time. For example, in a
car engine model, variables such as engine speed, throttle position, engine temperature,
and surrounding atmospheric conditions typically describe the operating point.

A *steady-state operating point* of a model, also
called an equilibrium or *trim* condition, includes
state variables that do not change with time. A model can have several steady-state
operating points. For example, a simple, damped pendulum has two steady-state operating
points at which the pendulum position does not change with time.

Use `sdo.OperatingPointSetup`

to set a model to steady-state as part
of model optimization or evaluation. This step is useful when you are performing
optimization or estimation using data measured when the system was at a non-zero steady
state. Matching the model state to the system state, used for data collection, helps
reduce model transients and improves results.

You need the Simulink^{®}
Control Design™ toolbox to use `sdo.OperatingPointSetup`

.

creates an `OpPointSetup`

= sdo.OperatingPointSetup(`opSpec`

,`inputsToUse`

,`statesToUse`

)`sdo.OperatingPointSetup`

object using the operating point
specifications `opSpec`

, inputs `inputsToUse`

, and
states `statesToUse`

.

object using additional arguments
specified using `findopOpts`

.
