Simulink Control Design™ - MathWorks

(Tuis.) #1

To specify multiple analysis points for linearization, create a vector of linearization I/O
objects.


Create an input perturbation analysis point at the output port of the Controller block.


io(1) = linio('magball/Controller',1);


Create an open-loop output analysis point at the output of the Magnetic Ball Plant block.
An open-loop output point is an output measurement followed by a loop opening.


io(2) = linio('magball/Magnetic Ball Plant',1,'openoutput');


View the specified analysis points.


io


1x2 vector of Linearization IOs:



  1. Linearization input perturbation located at the following signal:



  • Block: magball/Controller

  • Port: 1



  1. Linearization open-loop output located at the following signal:



  • Block: magball/Magnetic Ball Plant

  • Port: 1


You can use these analysis points to linearize only the Magnetic Ball Plant subsystem. To
do so, pass io to the linearize command or to an slLinearizer interface.
