Package: sdo.requirements
Settling time bound
Specify bounds on the real component of the poles of a linear
system. The real component of poles are used to approximate the settling
time. You can then optimize the model response to meet these bounds
using sdo.optimize.
You must have Simulink® Control Design™ software to specify settling time requirements.
settime_req = sdo.requirements.PZSettlingTimesdo.requirements.PZSettlingTime object and assigns default
values to its properties.
settime_req =
sdo.requirements.PZSettlingTime(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.PZSettlingTime('Type','>=') creates
an sdo.requirements.PZSettlingTime object
and specifies the Type property as a lower bound.

Settling time bound. Must be in seconds and a positive finite scalar. Default: |

Settling time bound type, specified as one of the following values:

| evalRequirement | Evaluate settling time bound on linear system |
Handle. To learn how handle classes affect copy operations, see Copying Objects.
Construct a settling time object and specify the settling time requirement.
r = sdo.requirements.PZSettlingTime; r.SettlingTime = 2.5;
Alternatively, you can specify the setting time during construction.
r = sdo.requirements.PZSettlingTime('SettlingTime',2.5);
Use getbounds to get the
bounds specified in a Check Pole-Zero Characteristics (Simulink Control Design) block.
