Examples

Basic Examples (3) 

Retrieve the model:

In[1]:=
ResourceData[\!\(\* TagBox["\"\<Fuel Slosh Model\>\"", #& , BoxID -> "ResourceTag-Fuel Slosh Model-Input", AutoDelete->True]\)]
Out[1]=

The icon:

In[2]:=
ResourceData[\!\(\* TagBox["\"\<Fuel Slosh Model\>\"", #& , BoxID -> "ResourceTag-Fuel Slosh Model-Input", AutoDelete->True]\), "Icon"]
Out[2]=

The annotation:

In[3]:=
ResourceData[\!\(\* TagBox["\"\<Fuel Slosh Model\>\"", #& , BoxID -> "ResourceTag-Fuel Slosh Model-Input", AutoDelete->True]\), "Annotation"]
Out[3]=

Available content elements:

In[4]:=
\!\(\* TagBox[ RowBox[{"ResourceObject", "[", "\"\<Fuel Slosh Model\>\"", "]"}], #& , BoxID -> "ResourceTag-Fuel Slosh Model-Input", AutoDelete->True]\)["ContentElements"]
Out[4]=

The available model types:

In[5]:=
ResourceData[\!\(\* TagBox["\"\<Fuel Slosh Model\>\"", #& , BoxID -> "ResourceTag-Fuel Slosh Model-Input", AutoDelete->True]\), "AvailableModelTypes"]
Out[5]=

The operating point:

In[6]:=
ResourceData[\!\(\* TagBox["\"\<Fuel Slosh Model\>\"", #& , BoxID -> "ResourceTag-Fuel Slosh Model-Input", AutoDelete->True]\), "OperatingPoint"]
Out[6]=

The parameters:

In[7]:=
ResourceData[\!\(\* TagBox["\"\<Fuel Slosh Model\>\"", #& , BoxID -> "ResourceTag-Fuel Slosh Model-Input", AutoDelete->True]\), "Parameters"]
Out[7]=

A transfer-function model of the system:

In[8]:=
tfm = TransferFunctionModel[ResourceData[\!\(\* TagBox["\"\<Fuel Slosh Model\>\"", #& , BoxID -> "ResourceTag-Fuel Slosh Model-Input", AutoDelete->True]\), "TransferFunctionModel"] /. ResourceData[\!\(\* TagBox["\"\<Fuel Slosh Model\>\"", #& , BoxID -> "ResourceTag-Fuel Slosh Model-Input", AutoDelete->True]\), "Parameters"], SystemsModelLabels -> {{\[ScriptR], Subscript[\[ScriptF], 1], Subscript[\[ScriptF], 2]}, {\[Theta], \[Psi], \[Omega], \[Gamma]}}]
Out[8]=

Obtain the transfer function of the thruster input 𝒻2 to the pendulum position ψ:

In[9]:=
tfmP = SystemsModelExtract[tfm, 3, 2]
Out[9]=

Its Bode plot:

In[10]:=
BodePlot[tfmP]
Out[10]=

Only six of the eight states are controllable:

In[11]:=
ssm = ResourceData[\!\(\* TagBox["\"\<Fuel Slosh Model\>\"", #& , BoxID -> "ResourceTag-Fuel Slosh Model-Input", AutoDelete->True]\), "StateSpaceModel"];
In[12]:=
{MatrixRank[ControllabilityMatrix[ssm]], SystemsModelOrder[ssm]}
Out[12]=

Determine indices of state pairs that are uncontrollable:

In[13]:=
notC = Select[Subsets[Range[8], {2}], ControllableModelQ[SystemsModelDelete[ssm, None, None, #]] &]
Out[13]=

The corresponding states:

In[14]:=
Grid[Table[Part[{ \[Theta][t], \[Psi][t], x[t], z[t], \[Omega][t], \[Gamma][t], vx[t], vz[t]}, i], {i, notC}], Sequence[ Frame -> True, FrameStyle -> GrayLevel[0.5], Background -> {None, {{ RGBColor[0.88, 1, 0.88], RGBColor[1, 0.85, 0.85]}}}]]
Out[14]=

The subsystem with the third pair of uncontrollable states removed:

In[15]:=
SystemsModelDelete[ssm, None, None, notC[[3]]]
Out[15]=

It is controllable:

In[16]:=
ControllableModelQ[%]
Out[16]=
