Package: sdo.requirements
Natural frequency bound
Specify bounds on the natural frequency of the poles of a linear
system. You can then optimize the model response to meet these bounds
using sdo.optimize
.
You must have Simulink® Control Design™ software to specify natural frequency requirements.
creates a pznatfreq_req
= sdo.requirements.PZNaturalFrequencysdo.requirements.PZNaturalFrequency
object and
assigns default values to its properties.

(Name,Value
)Name,Value
pair arguments.
Name
is a property name and
Value
is the corresponding
value. Name
must appear inside single
quotes (''
). You can specify several
name-value pair arguments in any order as
Name1,Value1,...,NameN,ValueN
.
Specify optional
comma-separated pairs of Name,Value
arguments. Name
is
the argument name and Value
is the corresponding value.
Name
must appear inside quotes. You can specify several name and value
pair arguments in any order as
Name1,Value1,...,NameN,ValueN
.
Use Name,Value
arguments to specify properties of the
requirement object during object creation. For example, requirement
= sdo.requirements.PZNaturalFrequency('Type','>=')
creates
an sdo.requirements.PZNaturalFrequency
object
and specifies the Type
property as a lower bound.

Frequency units of the requirement, specified as one of the following values:

Requirement name, specified as a character vector. Default: |

Natural frequency bound. Must be in radians/second and a positive finite scalar. Default: |

evalRequirement | Evaluate natural frequency bound on linear system |
Handle. To learn how handle classes affect copy operations, see Copying Objects.
Construct a natural frequency object and specify the natural frequency.
r = sdo.requirements.PZNaturalFrequency; r.NaturalFrequency = 1;
Alternatively, you can specify the natural frequency during construction.
r = sdo.requirements.PZNaturalFrequency(... 'NaturalFrequency',1);
Use getbounds
to get the
bounds specified in a Check Pole-Zero Characteristics (Simulink Control Design) block.
