Simulink® Response Optimization™

Response Optimization Using Simulink Control Design Software

Users with Control System Toolbox and Simulink Control Design software can perform frequency domain based optimization of Simulink models.

You can use Simulink Control Design software to configure SISO Tool with compensators, inputs, outputs, and loops computed from a Simulink model (see Designing Compensators in Simulink Control Design User's Guide). Once SISO Tool is configured with data from a Simulink model, you can use Simulink Response Optimization software to optimize SISO Tool based models.

There is only one difference when tuning compensators derived from Simulink Control Design software: The tuning of compensators from a Simulink model is done through the masks of the Simulink blocks representing each compensator. When selecting parameters to optimize, users can tune the compensator in the pole, zero, or gain format, or in a format consistent with the Simulink block mask as shown in the following figure. Changing the compensator format is not possible when optimizing pure SISO Tool models (those not derived using Simulink Control Design software).

To walk through a Simulink Response Optimization example using Simulink Control Design software, and the SISO Tool, see the tutorial "Enforcing Time and Frequency Requirements on a Single Loop Controller Design " and Simulink Response Optimization demo, airframe_demo (both in the Demos pane of the Help browser), which is based on a SISO Tool session started using Simulink Control Design software.
