DynamicSystems[Controllable] - determine controllability of a state-space system

Calling Sequence

Controllable( sys, opts )

Parameters

sys

-

System(ss); system object to test

opts

-

(optional) equation(s) of the form option = value; specify options for the Controllable command

Description

• 

The Controllable command determines whether sys, a state-space system, is controllable.

• 

If sys is controllable, true is returned, otherwise false is returned.

• 

Two methods, selected by the method option, are available for determining controllability.

• 

The staircase method applies the controllable staircase transform to the A and B Matrices of sys. If the state matrix of the resulting controllable subsystem has the same dimension as A, the system is controllable, otherwise it is uncontrollable.

• 

The rank method constructs the controllability matrix of sys system using the DynamicSystems[ControllabilityMatrix] command. If the matrix has full rank, the system is controllable, otherwise, it is uncontrollable.

• 

An error occurs if sys is not a state-space system.
