To open Control System Designer, in the Simulink model window, select Analysis >
Control Design > Control System Designer.In the Edit Architecture dialog box, on the Blocks tab, click Add Blocks. In the Select
Blocks to Tune dialog box, select the following blocks, and click OK.- scdairframectrl/q Control/q Gain
- scdairframectrl/az Control/az Gain
- scdairframectrl/az Control/az DTF
On the Signals tab, the analysis points defined in the Simulink model are automatically
added as Locations.- Input: scdairframectrl/Step az - Output port 1
- Output: scdairframectrl/Airframe Model - Output port 1
To use the selected blocks and signals, click OK.In the Data Browser, the Responses section contains the following open-loop responses,
which Control System Designer automatically recognizes as potential feedback loops
for open-loop design.- Output port 1 of scdairframectrl/az Control/az DTF
- Output port 1 of scdairframectrl/az Control/az Gain
