ssdata (Control Design and Simulation Module, MathScript Function)
Member of the info class.
Syntax
A = ssdata(SysInSS)
[A, B] = ssdata(SysInSS)
[A, B, C] = ssdata(SysInSS)
[A, B, C, D] = ssdata(SysInSS)
[A, B, C, D, Ts] = ssdata(SysInSS)
Description
Returns information about a state-space system model.
Inputs
| Name | Description |
| SysInSS | Specifies a linear time-invariant (LTI) model in state-space form. |
Outputs
| Name | Description |
| A | Returns the n x n state matrix of the SysInSS model, where n is the number of states. A is a real matrix. |
| B | Returns the n x m input matrix of the SysInSS model, where m is the number of inputs. B is a real matrix. |
| C | Returns the r x n output matrix of the SysInSS model, where r is the number of outputs. C is a real matrix. |
| D | Returns the r x m direct transmission matrix of the SysInSS model. D is a real matrix. |
| Ts | Returns the sampling time of the SysInSS model. If the value of Ts is 0, the SysInSS model is continuous. Otherwise, the model is discrete. Ts is a real scalar. |
Examples
A = [1, 1; -1, 2]B = [1, 2]'
C = [2, 1]
D = 0
SysInSS = ss(A, B, C, D)
[A, B, C, D, Ts] = ssdata(SysInSS)
