| Parameter | Description |
|---|---|
| A | State matrix: Nx-by-Nx matrix. |
| B | Input-to-state matrix: Nx-by-Nu matrix. |
| Ts | Sample time: positive scalar. |
| sysc | Continuous-time dynamic system: LTI model. |
| method | Discretization method: 'zoh', 'tustin', 'prewarp' |
| w0 | prewarp frequency. |
| Parameter | Description |
|---|---|
| P | phi |
| G | gamma |
| sysd | Discrete-time model |
The function sysd = c2d(sysc, Ts) discretizes the continuous-time dynamic system model sysc using a zero-order hold on the inputs with a sample time of Ts.
For instance, you can use sysd = c2d(sysc, Ts, method) to explicitly specify the discretization method.
A = [1 0.5; 0.5 1 ];
B = [0 -1; 1 0 ];
C = [ -1 0; 0 1 ];
D = [ 1 0; 0 -1 ];
sys = ss(A, B, C, D);
Ts = 2;
