| Description |
The code computes the optimal reduced order state space model for a given system represented in state space.
The method used to find the reduced order model is based on the paper by Chidambara.
M. R. Chidambara and E. J. Davison, " Further remarks on simplifying linear dynamical systems", IEEE Trans. Auto. Contr. (Correspondence), Vol. 12, pp. 213-214, Apr. 1967.
[A_1,B_1,C_1,D_1,r_opt]=reduced_model(A,B,C,D);
would result in ss(A_1,B_1,C_1,D_1) being the optimal reduced order model for the state space ss(A,B,C,D). The optimal order is given in the output variable r_opt. |
