When Control System Designer opens, it adds any analysis points previously defined in
the Simulink model to the Locations list. For the watertank_comp_design, there are
two such signals.
- Desired Water Level block output — Reference signal for the closed-loop step response
- Water-Tank System block output — Output signal for the closed-loop step response
To linearize the Simulink model and set the control architecture, click OK.
By default, Control System Designer linearizes the plant model at the model initial
conditions.
The app adds the PID controller to the Data Browser, in the Controllers and Fixed
Blocks area. The app also computes the open-loop transfer function at the output of the
PID Controller block, and adds this response to the Data Browser.
