CD Minimal State Realization VI

Owning Palette: Model Reduction VIs

Requires: Control Design and Simulation Module

Calculates a reduced State-Space Model based on null rows and columns in the controllability and observability matrices, respectively. Even though the controllability and observability matrices might be rank deficient, state elimination only occurs when columns or rows on such matrices are below a tolerance.

Details  

	State-Space Model contains a mathematical representation of and information about the system of which this VI reduces the states.
	Tolerance is the threshold this VI uses to determine if a row or column of the controllability or observability matrix is null. The default is 2E–16.
	error in describes error conditions that occur before this node runs. This input provides standard error in functionality.
	Reduced Model returns the minimal state-space realization. To access and modify the data in the model, use the Model Information VIs.
	Removed States returns the index number of the states that this VI eliminated from the original system. The index is zero-based.
	error out contains error information. This output provides standard error out functionality.
