20.6.5.3. Discrete State Space
The Discrete State-Space block implements the system defined by
\(\mathbf{x(n+1)}=\mathbf{A}\mathbf{x(n)}+\mathbf{B}\mathbf{u(n)}\)
\(\mathbf{y(n)}=\mathbf{C}\mathbf{x(n)}+\mathbf{D}\mathbf{u(n)}\)
- where,
- \(u\) is the input signal\(x\) is the state vector\(y\) is the output signal.

Parameter(s) |
Description |
\(\mathbf{A}\), \(\mathbf{B}\), \(\mathbf{C}\), \(\mathbf{D}\) |
Enter the matrix coefficients. |
Initial conditions |
Enter the initial state vector. |
Sample time |
Enter the time interval between samples. |
Import large scale State Matrix |
When a State Matrix file made by RecurDyn/Linear is very large, this option does not display the data for \(\mathbf{A}\), \(\mathbf{B}\), \(\mathbf{C}\), \(\mathbf{D}\). |
State Matrix Import |
Displays the data in \(\mathbf{A}\), \(\mathbf{B}\), \(\mathbf{C}\), \(\mathbf{D}\) after reading a State Matrix file made by RecurDyn/Linear. |
