Version 6.2 (R14SP2) Control System Toolbox™ Software Release Notes

Version 6.2 (R14SP2) Control System Toolbox™ Software

This table summarizes what's new in Version 6.2 (R14SP2):

New features and changes introduced in this version are

• Command-Line API for Customizing Plots

• Constraint Types for SISO Design

• Bode and Nichols Plots Have Additional Options

• Model-Approximation and Order-Reduction Commands

Command-Line API for Customizing Plots

The Control System Toolbox™ software now provides a command-line API for customizing units, labels, limits, and other plot options. You can now change default plot options before generating a plot, or modify plot properties after creation.

For a detailed description of the commands, see the Control System Toolbox documentation.

Constraint Types for SISO Design

You can now create

• Single piecewise linear constraints for root-locus and Bode plots

• Gain/phase exclusion regions for Nichols plots

Design constraints are displayed as shaded regions.

Bode and Nichols Plots Have Additional Options

When editing Bode and Nichols plots, you can now

• Set the lower limit of the magnitude manually.

• Adjust the phase offsets by multiples of 360 degrees to facilitate comparing multiple responses.

Model-Approximation and Order-Reduction Commands

New commands have been added for model approximation and order reduction:

• hsvd computes and plots the Hankel singular values.

• balred computes low-order approximations using a numerically stable, balancing-free algorithm. You can perform multiple order reductions with a single command.
