CD Model Order Reduction VI

Owning Palette: Model Reduction VIs

Requires: Control Design and Simulation Module

Eliminates state dynamics that you want to ignore in the State-Space Model. This VI can eliminate the state dynamics by deleting the states or by assuming steady state conditions for states with fast dynamics, also known as pseudo-steady-state assumption. The pseudo steady state assumption does not affect the discrete and continuous system gain of the original system, that is, the remaining states will have the same gain as when considering the full order system.

Details  

	State-Space Model contains a mathematical representation of and information about the system of which this VI reduces the states.
	States lists the index number of the states you want to eliminate. The index is zero-based.
	Procedure determines how to eliminate the states. 0 Match Gain (default)—The VI considers the states, which you want to eliminate, to be in a steady state. This VI substitutes the steady state values of the removed states into the dynamics of the reduced order system. 1 Simple Detection—The VI removes the states from the system model.
	error in describes error conditions that occur before this node runs. This input provides standard error in functionality.
	Reduced Model is the resulting reduced State-Space Model. To access and modify the data in the model, use the Model Information VIs.
	error out contains error information. This output provides standard error out functionality.
