These blocks are available in the Continuous and Discrete Simulink libraries. For more information on tuning PID Controller using the PID Tuner, see "Automatic PID Tuning". 7 Simulink® Control DesignTM Release Notes New Automated PID Tuning Algorithm You can now tune compensators using a new automated PID tuning algorithm called Robust Response Time, which is available in the SISO Design Task. For more information, see the linlft and linlftfold reference pages. Ability to Set Default Plot Type for Linear Analysis Results from GUI You can now set the default plot type for viewing linear analysis results computed in the Control and Estimation Tools Manager. This setting applies to all future Control and Estimation Tools Manager sessions. To set this option in the Simulink Control Design Preferences, select File > Preferences in the Control and Estimation Tools Manager. 9 Simulink® Control DesignTM Release Notes Version 2. 5 (R2009a) Simulink Control Design Software This table summarizes what's new in Version 2. 5 (R2009a): New Features and Changes Yes Details below Version Compatibility Considerations No Fixed Bugs and Known Problems Bug Reports Includes fixes Related Documentation at Web Site No New features and changes introduced in this version are · "Ability to Generate MATLAB Code from the GUI for Creating Operating Points and Linearizing Models" on page 10 · "Ability to Tune Additional Blocks" on page 10 · "New Option for Labeling Bus Signal I/O Names in Linearization Results" on page 11 Ability to Generate MATLAB Code from the GUI for Creating Operating Points and Linearizing Models You can now generate MATLAB code reflecting the configuration in the GUI when creating operating points and linearizing models. For information on how to generate code, see the following sections in the Simulink Control Design documentation: · "Creating Operating Points" · "Linearizing at an Operating Point" Ability to Tune Additional Blocks You can now tune the following blocks: · Blocks that you discretized using the Simulink Model Discretizer · Blocks in the Simulink Extras library that specify initial states or outputs 10 Version 2. 5 (R2009a) Simulink® Control DesignTM Software For information about how to tune these blocks, see "Selecting Blocks to Tune" in the Simulink Control Design documentation. New Option for Labeling Bus Signal I/O Names in Linearization Results You can now compute linear models that show the bus signal names for linearization I/O points located on buses. You can select this option using the following: · Linearization Options GUI See "Choosing Linearization Settings and Algorithms" in the Simulink Control Design User's Guide. · linoptions command See the linoptions reference page. 11 Simulink® Control DesignTM Release Notes Version 2. 4 (R2008b) Simulink Control Design Software This table summarizes what's new in Version 2. 4 (R2008b): New Features and Changes Yes Details below Version Compatibility Considerations No Fixed Bugs and Known Problems Bug Reports Includes fixes Related Documentation at Web Site No New features and changes introduced in this version are · "New Upsampling Option for Rate Conversion When Linearizing Simulink Models" on page 12 · "Ability to Specify State Order of Linearized Models from the Command Line" on page 13 · "Ability to Filter the Linearization Inspector to Show Blocks in the Linearization Path" on page 13 · "Ability to Disable the Calculation of Linearization Diagnostics and Inspector Data in the GUI" on page 13 New Upsampling Option for Rate Conversion When Linearizing Simulink Models Version 2. 4 includes an upsampling rate conversion method for linearization. This method upsamples discrete-time LTI systems at any sampling rate that is an integer-value-times faster than the sampling rate of the original system. You can select the upsampling rate conversion method in the following ways: · Using the linearization options GUI · From the command line using linoptions For more information on the upsampling rate conversion method, see "Choosing Linearization Settings and Algorithms" and the linoptions reference page. 12 Version 2. 4 (R2008b) Simulink® Control DesignTM Software Ability to Specify State Order of Linearized Models from the Command Line You can now specify the order of the states in your linearized model directly from the command line using the linearize command. Previously, you could only specify state order using the GUI. For more information on specifying state order from the command line, see the linearize reference page. Ability to Filter the Linearization Inspector to Show Blocks in the Linearization Path You can now filter the list of blocks in the Linearization Inspector to show only the blocks in the linearization path. This filtering makes it easier for you to find blocks in the linearization path that you want to inspect. For information using the Linearization Inspector to inspect blocks in the linearization path, see "Inspecting the Linearization Results Block by Block". Ability to Disable the Calculation of Linearization Diagnostics and Inspector Data in the GUI You can now disable the calculation of the linearization inspector and diagnostics information when you linearize using the GUI. This capability allow you to choose when you want to calculate diagnostic information. For more information on disabling the linearization inspector, see "Choosing Linearization Settings and Algorithms". 13 Simulink® Control DesignTM Release Notes Version 2. 3 (R2008a) Simulink Control Design Software This table summarizes what's new in Version 2. 3 (R2008a): New Features and Changes Yes Details below Version Compatibility Considerations No Fixed Bugs and Known Problems Bug Reports Includes fixes Related Documentation at Web Site No New features and changes introduced in this version are · "New Diagnostic Messages Help You Troubleshoot Linearization Results" on page 14 · "Ability to Find Operating Points for Simscape Models" on page 15 · "Updated Error and Warning Message System" on page 15 New Diagnostic Messages Help You Troubleshoot Linearization Results You can now view diagnostic messages for your linearized model that help you diagnose and troubleshoot linearization results. These messages identify blocks in your model that encounter the following block issues during linearization: · Blocks that have been marked as not supported for linearization · Blocks with linearization configuration warning messages · Blocks without pre-programmed exact Jacobian that linearize using numerical approximation For more information on diagnostic messages, see "Diagnosing Blocks" in the Simulink Control Design User's Guide. 14 Version 2. 3 (R2008a) Simulink® Control DesignTM Software Ability to Find Operating Points for Simscape Models You can now find operating points for models that include SimscapeTM and SimHydraulics® blocks using the Simulink Control Design findop command. For more information on finding operating point for Simscape Models, see the Simscape documentation. Updated Error and Warning Message System The Simulink Control Design error and warning IDs and messages have been updated. If you use error and warning IDs in your code, you must update your code to reflect the new IDs. 15 Simulink® Control DesignTM Release Notes Version 2. 2 (R2007b) Simulink Control Design Software This table summarizes what's new in Version 2. 2 (R2007b): New Features and Changes Yes Details below Version Compatibility Considerations No Fixed Bugs and Known Problems Bug Reports Includes fixes Related Documentation at Web Site No New features and changes introduced in this version are · "Ability to Linearize Models with Model-Reference Blocks by Any Linearization Method" on page 16 · "Ability to Design Compensators for Models Containing Model-Reference Blocks" on page 17 · "Ability to Generate Linearized Models with Exact Time-Delay Representations" on page 17 · "Ability to Linearize Periodic Function-Call Subsystems" on page 17 Ability to Linearize Models with Model-Reference Blocks by Any Linearization Method You can now perform any type of linearization for models containing Model blocks that reference other Simulink models.
