New features and changes introduced in this version are
New Parallel Computing Support For Frequency Response Estimation
New Commands Support Recomputing Frequency Response Estimation Results at Specific Frequencies
New frest.simcompare Output Argument Returns Simulation Output Data From Linear System
New Options in Simulink Results Viewer GUI for Viewing Frequency Response Estimation Results
New Option for Labeling Bus Signal I/O Names in the SISO Design Task
If you have the Parallel Computing Toolbox™ software installed, you can use parallel computing to speed up frequency response estimation.
For more information, see Speeding Up Estimation Using Parallel Computing in the Simulink Control Design documentation.
If you use the sinestream input signal for estimation, you can now recompute your frequency response estimation for only those specific frequencies that do not reach steady state. Previously, you had to redo the entire estimation if a few frequencies needed recomputing.
For more information, see Time Response Not at Steady State.
This release provides enhanced frest.simCompare functionality, which allows the return of simulated output data. If your linear model uses state-space representation, you can also return the state vector.
For more information, see the frest.simCompare reference page.
The Simulation Results Viewer GUI, which you display using frest.simView, now provides additional options for analyzing your frequency response estimation:
You can now enable phase unwrapping in the frequency response plot. To unwrap phase, right-click the Bode plot, and select Unwrap Phase.
You can also import frequency response estimation results into an open Simulation Results Viewer, which replaces the existing results. 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.
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 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.
The following Simulink blocks now have Analytic Jacobians, which are optimized for memory consumption in large-scale models:
Math Function (Transpose and Hermitian Transpose)
For more information on each block, see the block reference pages.
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
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.
