New features introduced in this version:

• Ability to Design Compensators for New Types of Plants

• New Automated PID Tuning Method

Ability to Design Compensators for New Types of Plants

In the SISO Design Tool, you can now design compensators for plants models that:

• Contain time delays

  Previously, you had to approximate delays before designing compensators.

• You specify as frequency-response data (FRD)

For more information on designing compensators using the SISO Design Tool, see SISO Design Tool.

New Automated PID Tuning Method

You can now tune compensators using a new automated PID tuning algorithm called Robust Response Time, which is available in the SISO Design Tool. You specify the open-loop bandwidth and phase margin, and the software computes PID parameters to robustly stabilize your system.

For information on tuning compensators using automated tuning methods, see Automated Tuning.
