ss2ss

Transforms a state-space model to another state-space model.

Syntax

SYSTOUT = ss2ss(SYSIN, T)

Inputs

SYSIN
A state space system.
T
A matrix; state coordinate transformation.

Outputs

SYSTOUT
Transformed state-space model.

Example

State Transformation including the function ss2ss: 
A = [0 1; -2/3 -8/3];
% Input and output matrices
B = [0; 1/3];
C = [1 0];
D = 0;
sys = ss(A, B, C, D)   % state space system
[T, D] = eig(A);       % Eigenvalues at eigenvectors of A
P = inv(T)             % Transformation matrix
modifiedss = ss2ss(sys, P)  % diagonal form
modifiedss = object [

Comments

SYST = ss2ss(SYS, T) returns a new state-space model SYSTOUT based on SYSIN and the state coordinate transformation T.

Please verify that the state coordinate transformation matrix T is invertible.
