Supported Design Requirements

Time- and frequency-domain requirements.

Specify Time-Domain Design Requirements in the Tool

Specify time-domain requirements such as lower and upper amplitude bounds, step response bounds, reference signals, elliptical bounds, and custom bounds.

Specify Variable Requirements in the Tool

Specify monotonic, smoothness, and relational constraints on variables in your model.

Specify Frequency-Domain Design Requirements in the Tool

Specify frequency-domain requirements, such as gain and phase margin bounds, closed-loop peak response bounds, step-response bounds, and custom bounds.

Specify Custom Requirements in the Tool

This topic shows how to specify custom requirements in the Response Optimization tool.

Move Constraints

Position bound edges graphically or by specifying a location.
