i want to import state space matrices from worksapce to state space block in simulink plz help regards.

Best Answer

You have not to import them, If your matrices are A,B,C and D, just set the SS block parameters to A, B, C and D

A=[-2 1;-3 0];
B=[0;1]
C=[1 0]
D=0
set_param('untitled/State-Space','A','A','B','B','C','C','D','D') 
% untitled is the name of your simulink model, 
%State-Space is the name of your State space block

MATLAB: Does simulink scale ill-conditioned matrices provided to State-Space block

The 'State-Space' block in Simulink does not perform automatic scaling for matrices that are entered as parameters.

However, most algorithms within the Control Systems Toolbox perform scaling to prevent drastic losses of accuracy as described in the following documentation link:
