Compatibility issues reported after the product release appear under Bug Reports at The MathWorksTM Web site. Bug fixes can sometimes result in incompatibilities, so review the fixed bugs in Bug Reports for any compatibility impact. Fixed Bugs and Known Problems The MathWorks offers a user-searchable Bug Reports database so you can view Bug Reports. The development team updates this database at release 2 Summary by Version time and as more information becomes available. Bug Reports include provisions for any known workarounds or file replacements. Information is available for bugs existing in or fixed in Release 14SP2 or later.

The user-defined options you use in the dksyn command now includes a new option MixedMU. Set this option to 'on' to account for real uncertain parameters in your system. For more information, see the dkitopt, and dksyn reference pages. New Command to Linearize Simulink Models with Uncertainty If you have Simulink® Control DesignTM software installed, you can take model uncertainty into account when linearizing a Simulink model. You can 5 Robust Control ToolboxTM Release Notes then use the resulting uncertain linearized model (uss object) to perform linear analysis and robust control design. If your model already contains Uncertain State Space blocks, use the new ulinearize command to obtain an uss model. If you want to account for uncertainty in your linear analysis without using Uncertain State Space blocks, you can specify individual Simulink blocks to linearize to an uncertain variable. For more information, see "Computing Uncertain State-Space Models from Simulink Models" in the Robust Control Toolbox User's Guide. New Interface for Simulating Effects of Uncertainty in Simulink Models This version of the product provides a new interface to simulate the effects of uncertainty in Simulink models. The interface includes the following: · Uncertain State Space block to specify uncertain system in Simulink. You should replace USS System blocks in your existing models with the Uncertain State Space block. [. . . ] See "New Interface for Simulating Effects of Uncertainty in Simulink Models" on page 6.
