EMI_GetProjectedContinuousStates (EMI Function)
Owning Class: Continuous States
Requires: Control Design and Simulation Module
Prototype
double* EMI_GetProjectedContinuousStates(emiRef model);
Description
Returns a pointer to the projected continuous states of an external model. You can call this function only within the EMI_CB_CalculateProjectedStates function.
When you use an ordinary differential equation (ODE) solver to solve a differential algebraic equation, you might need to project the continuous states of the model onto the integral constraint surface at each accepted major step. Use the EMI_GetProjectedContinuousStates function within the EMI_CB_CalculateProjectedStates function to modify the continuous states directly. The LabVIEW Control Design and Simulation Module calls the EMI_CB_CalculateProjectedStates function after completing any minor steps and before the next accepted major step.
Inputs
| Name | Description |
|---|---|
| model | Specifies a reference to the external model. Use this reference as an input to other EMI functions. Do not modify model directly. |
Return Value
Returns a pointer to the projected continuous states of the model.
Examples
void EMI_CB_CalculateProjectedStates(emiRef model) {
double* xc = EMI_GetProjectedContinuousStates(model);
if (xc[0] > 5.0) {
xc[0] = 5.0
}
}
