New features and changes introduced in this version are
New features for response plots include
Normalization of time plots for easy trend comparison.
Display of driving input signal in linear simulation (lsim) plots.
Standard zooming for all response plots.
The Full View right-click menu.
Ability to toggle magnitude and phase displays in Bode plots.
In Bode plots, a modified phase-correction algorithm that produces consistent phase at w=Inf and is robust to perturbations of the pole/zero structure at the origin.
Displaying only positive frequencies in Nyquist plots.
A new function, iopzmap, that plots the transfer poles and zeros for each I/O pair in a MIMO system.
The following are new features and enhancement in the LTI Viewer.
The LTI Viewer no longer restricts importing models with unequal numbers of inputs and/or an unequal numbers of outputs. You can import any combination of LTI models into the viewer.
The import and export dialog boxes are now easier to use.
The LTI Viewer now imports System Identification Toolbox™ SISO models. The noise model is automatically discarded and the idmodelis converted to ZPK format.
The zoom property in the LTI Viewer right-click menu has been removed. You can access this functionality from the new toolbar.
The following are new features in the SISO Design tool.
The SISO Design tool supports two new feedback structures:
Feedforward configuration
Cascade configuration with filter F in the minor loop
All the usual functionality (e.g., graphical tuning of F and G) is available in the new feedback structures.
The SISO Design tool contains a new Analysis menu that raises Loop Responses under Tools to the top level. New plots available from this menu are
Input disturbance rejection
Output disturbance rejection
LTI Viewers that are linked to the SISO Design tool update response plots in real-time during mouse-driven compensator tuning. This is the default behavior. To deactivate this feature, clear the Real-Time Update check box in the linked LTI Viewer. In this case, plots update only when you release the mouse button.
The SISO Design tool now imports System Identification Toolbox SISO models. The noise model is automatically discarded and the idmodel is converted to ZPK format.
A new window, the Design Archive, combines both store and retrieve functions within a single, more-intuitive GUI.
You can now trace the frequency by placing your mouse cursor over the Nichols contour.
The c2d function has a new impulse-invariant discretization method that guarantees matching continuous and discrete responses for pulse inputs.
The following bugs were fixed in this release:
The allmargin function converts ZPK models to TF format only when there is an algebraic loop in your system. This change ensures that the SISO Design tool can correctly diagnose closed-loop stability (open loop is always in ZPK format).
The dlinmod function now correctly linearizes all multirate discrete or hybrid (continuous and discrete) Simulink models when using Jacobian-based linearization.
Formerly, bad edge cases in the orthogonalization loop caused a divide by zero in the place function. This is no longer the case.
