ctrbmx (MathScript RT Module Function)
Owning Class: ssanals
Requires: Control Design and Simulation Module and MathScript RT Module
Syntax
Cb = ctrbmx(SysInSS)
Cb = ctrbmx(A, B)
Legacy Name: ctrb
Description
Calculates the controllability matrix of the SysInSS system model. You use the controllability matrix to determine if the given model is controllable. An n-th order model is controllable if the controllability matrix is full rank, meaning the rank of the controllability matrix equals n.
Inputs
| Name | Description |
|---|---|
| SysInSS | Specifies a linear time-invariant (LTI) model in state-space form. |
| A | Specifies an n x n state matrix, where n is the number of states. The default is an empty matrix. A is a real matrix. |
| B | Specifies an n x m input matrix, where m is the number of inputs. The default is an empty matrix. B is a real matrix. |
Outputs
| Name | Description |
|---|---|
| Cb | Returns the controllability matrix of the SysInSS model. Cb is a real matrix. |
Details
The following table lists the support characteristics of this function.
| Supported in the LabVIEW Run-Time Engine | Yes |
| Supported on RT targets | Yes |
| Suitable for bounded execution times on RT | Not characterized |
Examples
SysInSS = ss([1, 1; -1, 2], [1, 2]', [2, 1], 0)
Cb = ctrbmx(SysInSS)
