[. . . ] Previously, you had to open a new Viewer each time you viewed estimation results. To import results, select File > Import in the Simulation Results Viewer. New Option for Labeling Bus Signal I/O Names in the SISO Design Task You can now configure the SISO Design Task to automatically label model I/Os using bus signal names. Model I/O labels describe available loops in the Graphical Tuning tab and label response plots in the Analysis Plots tab of the 10 Version 3. 1 (R2010a) Simulink® Control DesignTM Software SISO Design Task GUI. Previously, labels for bus signals were based on the block and port path, or the Simulink signal name. To use this option, select Tools > Options in the SISO Design Task GUI, and enable Use bus signal names to label model I/O. Existing Simulink Blocks Now Have Analytic Jacobians The following Simulink blocks now have Analytic Jacobians, which are optimized for memory consumption in large-scale models: · Switch · Multiport Switch · Math Function (Transpose and Hermitian Transpose) For more information on each block, see the block reference pages. Change in Format of Time Series in frestimate Output When you use the simout output of the frestimate command, you obtain a cell array of Simulink. Timeseries objects. Previously, the time dimension was always the first dimension of each Simulink. Timeseries object. As of R2010a, the time dimension of each Simulink. Timeseries in simout is: · The first dimension, if the time series is 2-D · The last dimension, if the time series is 3-D or higher Compatibility Considerations If you have scripts that run frestimate on a model having an output point on a vector or matrix signal and perform operations on the resulting 3-D or higher-dimensional Simulink. Timeseries object in simout, modify your scripts to reflect the new placement of the time dimension in the time series.

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". 13 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. 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 "Completing the Design". Ability to Compute Frequency Response of Simulink Models You can now compute the frequency response of a Simulink model using simulation. You use new commands to easily create input signals and simultaneously simulate and estimate the frequency response without changing your model. You can also use this capability to validate the accuracy of exact linearizations. Ability to Specify the Linearization of Simulink Blocks You can now specify the linearization of Simulink blocks, subsystems, and model references without having to replace any block in your model. You can specify the linearizations as LTI models or Robust Control Toolbox uncertain models. Ability to Design Compensators for Plant Models With Time Delays You can now design compensators for plants with exact time delay representations. Previously, you had to specify a Padé approximation before designing compensators. For more information on designing compensators for plants with time delays, see "Designing Compensators for Plants with Time Delays". 14 Version 3. 0 (R2009b) Simulink® Control DesignTM Software New Commands to More Efficiently Compute Multiple Linearizations You can now more efficiently compute multiple linearizations for large models when only a few blocks or model references change per linearization. You linearize the fixed portion of the model once using linlft and linearize the varying portion multiple times. Then, you combine the results using linlftfold to obtain linearizations equal to those you would receive if you linearized the entire model multiple times. 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. 15 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 16 · "Ability to Tune Additional Blocks" on page 16 · "New Option for Labeling Bus Signal I/O Names in Linearization Results" on page 17 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. 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 For information about how to tune these blocks, see "Selecting Blocks to Tune" in the Simulink Control Design documentation. 16 Version 2. 5 (R2009a) Simulink® Control DesignTM Software 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.

View Linearizations in the Control and Estimation Tools Manager You can view state space, transfer function, and zero-pole gain representations of linearized models within the Control and Estimation Tools Manager without exporting to the workspace. These linearized models appear in the linearization summary pane of the Control and Estimation Tools Manager. 30 Version 1. 2 (R14SP2) Simulink® Control DesignTM Software Discretization Methods Added You can select from three different discretization methods for linearization of multirate and hybrid models. List of Blocks with Preprogrammed Analytic Jacobians Added You can view a complete list of blocks indicating which blocks have preprogrammed analytic Jacobians for use with the block-by-block analytic linearization algorithm. Block Name Readability Improved You can use either truncated block names or full block names in the state space matrices of a linearized model, and within the LTI Viewer, to improve readability. 31 Simulink® Control DesignTM Release Notes Version 1. 1 (R14SP1) Simulink Control Design Software This table summarizes what's new in Version 1. 1 (R14SP1): New Features and Changes No Version Compatibility Considerations No Fixed Bugs and Known Problems Fixed bugs Related Documentation at Web Site No 32 Version 1. 0 (R14) Simulink® Control DesignTM Software Version 1. 0 (R14) Simulink Control Design Software This table summarizes what's new in Version 1. 0 (R14): New Features and Changes Yes Details below Version Compatibility Considerations No Fixed Bugs and Known Problems No bug fixes Related Documentation at Web Site No New features and changes introduced in this version are About the Simulink Control Design Software The Simulink Control Design software provides tools for the linearization of control systems and models.
