New features and changes introduced in this version are
Control System Toolbox software now lets you:
Model, simulate, and analyze any interconnection of linear systems with delays, such as systems containing feedback loops with delays.
Exactly analyze and simulate control systems with long delays. You can evaluate control strategies, such as Smith Predictor and PID control for first-order-plus-dead-time plants.
Use new commands for modeling state-space models with delays including: delayss, getDelayModel, and setDelayModel.
For more information, see the section on Models with Time Delays in the Control System Toolbox documentation.
Control System Toolbox software now provides the following new and updated automated tuning methods:
New Singular Frequency Based Tuning lets you design PID compensators for both stable and unstable plants.
New H-infinity Loop Shaping lets you find compensators based on a desired open-loop bandwidth or loop shape. This feature requires Robust Control Toolbox software.
Updated Internal Model Control (IMC) Tuning now supports unstable plants.
For more information, see the section on automated tuning in the Control System Toolbox documentation.
The d2d function now includes the following new options for the resampling method:
'tustin'—Performs Bilinear (Tustin) approximation
'prewarp'—Performs Tustin approximation with frequency prewarping
For more information, see the d2d reference pages.
