*SetControlSISOInput()

Sets the input to the transfer function of the controller.

Syntax

*SetControlSISOInput(varname, val)

Arguments

varname: The variable name of the ControlSISO being set.; Data type: varname
val: The value or expression describing the input to the transfer function.; Data type: real

Example

*BeginMdl( model5, "MBD Model" ) 
 *ControlSISO( siso_0, "ControlSISO 0" )
 *SolverVariable( sv_0, "Reference Speed" )
 *ActionReactionForce( frc_0, "Force 0", ROT, MODEL.b_0, 
 MODEL.B_Ground, MODEL.p_0, 
 Global_Frame )
 *SetSolverVariable(sv_0, 3)
 *SetForce(frc_0, 0, 0, '{MODEL.siso_0.OUTPUT}')
 *SetControlSISOCoeffs(siso_0, NUMER, 2, 10.00, 1.00, 
 DENOM, 2, 0.00, 1.00)
 *SetControlSISOInput(siso_0, '-WZ({MODEL.b_0.cm.idstring})
 +{sv_0.value}')
*EndMdl()

Context

*BeginMDL()

*DefineAnalysis()

*DefineSystem()

Comments

The input to the controller is most often a signal from the mechanism model that is a function of one or more state variables.
