ss

State-space model.

Syntax

• sys = ss(A, B, C, D)
• sys = ss(A, B, C, D, TS)
• sys = ss(D)
• sys = ss(sysIn)

Input argument

• A - State matrix: Nx-by-Nx matrix.
• B - Input-to-state matrix: Nx-by-Nu matrix.
• C - State-to-output matrix: Ny-by-Nx matrix.
• D - Feedthrough matrix: Ny-by-Nu matrix.
• TS - Sample time: scalar.
• sysIn - SISO LTI model.

Output argument

• sys - Output state space system model.

Description

Creates a continuous-time state-space model using matrices A, B, C, and D, allowing for either real or complex-valued matrices.

This model is represented as sys = ss(A, B, C, D).

Examples

A = [-15,-20; 10, 0];
B = [5; 0];
C = [0, 1];
D = 0;
sys = ss(A, B, C, D)

num = [3 4];
den = [3 1 5];
Ts = 0.2;
sysIn = tf(num, den, Ts)
sys = ss(sysIn)
