Interactive root locus plot of the specified SISO system SYS.
This functions
directly calls rlocus() from the control package
which must be installed and loaded.
In contrast to rlocus(), mouse clicks on the root locus display
the related gain and all other poles resulting from this gain
together with damping and frequency of conjugate complex pole pairs.
All possible interaction by mouse clicks or keys are:
Displays related gain and all resulting closed loop poles together with damping and frequency
Simulates the step response for the gain of of the most recently selected pole locations
Simulates the impulse response for the most recently selected gain
Provides the open loop bode plot for the most recently selected gain
Provides the open loop bode plot with stability margins for the most recently selected gain
Provide sall four aforementioned plots
Removes all closed loop pole markers and annotations
Removes all open figures with simulation and bode plots
Exits the interactive mode and re-activates the octave prompt
There are no output parameters.
Inputs
LTI model. Must be a single-input and single-output (SISO) system.
The increment used in computing gain values.
Minimum value of k.
Maximum value of k.
Outputs
Plots the interactive root locus to the screen.
Unlike rlocus(), this function does not have any output parameters.
For output parameters please directly use rlocus().
