dss
Create descriptor state-space models
Syntax
sys = dss(A,B,C,D,E)
sys = dss(A,B,C,D,E,Ts)
sys = dss(A,B,C,D,E,ltisys)
Description
sys = dss(A,B,C,D,E)
creates
the continuous-time descriptor state-space model
The output sys
is an SS model storing the
model data (see State-Space Models). Note that ss
produces
the same type of object. If the matrix D = 0,
you can simply set d
to the scalar 0
(zero).
sys = dss(A,B,C,D,E,Ts)
creates the discrete-time descriptor model
with sample time Ts
(in seconds).
sys = dss(A,B,C,D,E,ltisys)
creates a descriptor model with properties inherited from the LTI model ltisys
(including
the sample time).
Any of the previous syntaxes can be followed by property name/property value pairs
'Property',Value
Each pair specifies a particular LTI property of the model,
for example, the input names or some notes on the model history. See set
and the example below for details.
Examples
The command
sys = dss(1,2,3,4,5,'inputdelay',0.1,'inputname','voltage',... 'notes','Just an example');
creates the model
with a 0.1 second input delay. The input is labeled 'voltage'
,
and a note is attached to tell you that this is just an example.
