Package: sdo.requirements
Closed loop peak gain bound
Specify lower or equality bounds on the closed loop peak gain
of a linear system. The closed loop can be formed using negative,
positive or no feedback. You can then optimize the model response
to meet these bounds using sdo.optimize
.
You must have Simulink® Control Design™ software to specify closed-loop peak gain bounds.
creates a pkgain_req
= sdo.requirements.ClosedLoopPeakGain sdo.requirements.ClosedLoopPeakGain
object and assigns
default values to its properties.
uses additional options specified by one or more pkgain_req
=
sdo.requirements.ClosedLoopPeakGain(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.ClosedLoopPeakGain('Type','<=')
creates
an sdo.requirements.ClosedLoopPeakGain
object
and specifies the Type
property as an upper bound.

Handle. To learn how handle classes affect copy operations, see Copying Objects.
Construct a closed loop peak gain object and specify peak gain requirement.
r = sdo.requirements.ClosedLoopPeakGain; r.PeakGain = 2;
Alternatively, you can specify the peak gain during construction:
r = sdo.requirements.ClosedLoopPeakGain('PeakGain',2);
Use getbounds
to get the
bounds specified in Check Nichols Characteristics (Simulink Control Design) block.
