Converts a simulation model into a model you can use for control design. You can use this polymorphic VI to convert state-space, transfer function, zero-pole-gain, SISO transfer function, and SISO zero-pole-gain models. You must manually select the polymorphic instance to use.

Note  You can use simulation models you created using the LabVIEW Simulation Module with this VI.

CD Convert Simulation to Control Design (State-Space)

	Simulation State-Space Model represents the simulation model this VI converts into a control design model. You can create a simulation model using the LabVIEW Simulation Module and use the model with the LabVIEW Control Design Toolkit.
	Sampling Time [dt] (s) specifies the sampling time of the model. Sampling Time [dt] (s) defines whether the model represents a continuous-time system or a discrete-time system. If the model represents a continuous-time system, Sampling Time [dt] (s) must equal zero. If the model represents a discrete-time system, Sampling Time [dt] (s) must be greater than zero and equal to the sampling rate, in seconds, of the discrete system. The default is 0.
	error in describes error conditions that occur before this VI or function runs. The default is no error. If an error occurred before this VI or function runs, the VI or function passes the error in value to error out. This VI or function runs normally only if no error occurred before this VI or function runs. If an error occurs while this VI or function runs, it runs normally and sets its own error status in error out. Use the Simple Error Handler or General Error Handler VIs to display the description of the error code. Use error in and error out to check errors and to specify execution order by wiring error out from one node to error in of the next node. status is TRUE (X) if an error occurred before this VI or function ran or FALSE (checkmark) to indicate a warning or that no error occurred before this VI or function ran. The default is FALSE. code is the error or warning code. The default is 0. If status is TRUE, code is a nonzero error code. If status is FALSE, code is 0 or a warning code. source specifies the origin of the error or warning and is, in most cases, the name of the VI or function that produced the error or warning. The default is an empty string.
	State-Space Model returns the control design model equivalent of a simulation model. You can create a simulation model using the LabVIEW Simulation Module and use the model with the Control Design Toolkit.
	error out contains error information. If error in indicates that an error occurred before this VI or function ran, error out contains the same error information. Otherwise, it describes the error status that this VI or function produces. Right-click the error out front panel indicator and select Explain Error from the shortcut menu for more information about the error. status is TRUE (X) if an error occurred or FALSE (checkmark) to indicate a warning or that no error occurred. code is the error or warning code. If status is TRUE, code is a nonzero error code. If status is FALSE, code is 0 or a warning code. source describes the origin of the error or warning and is, in most cases, the name of the VI or function that produced the error or warning.

CD Convert Simulation to Control Design Details

This VI does not support delays because simulation models do not directly include delay in their representation of a system. When converting a simulation model to a control design model, this VI does not transfer delay to the control design model. To account for the delays, you must linearize the simulation model before converting it. Refer to the LabVIEW Control Design Toolkit User Manual for more information about delays.
