Description

Properties for a Differential Corrector profile.

Public Properties

ClearCorrectionsBeforeRun	Clear Corrections Before Each Run - if true, the differential corrector is automatically reset each time that it is run, discarding information that was computed the last time it was run.
ControlParameters	Get the list of control parameters defined for the profile.
ConvergenceCriteria	Gets or sets the convergence criteria.
DerivativeCalcMethod	Gets or sets the derivative calculation method.
DrawPerturbation	Defines the display of perturbations in the 2D and 3D Graphics windows, if you have set Astrogator to draw while calculating.
EnableBPlaneNominal	If true, Astrogator will update the display of B-Planes for the nominal run of each iteration during the targeting process.
EnableBPlanePerturbations	If true, Astrogator will update the display of B-Planes for both of the perturbations of each iteration during the targeting process.
EnableDisplayStatus	If true, a page will appear during the targeting run to report the status of the targeting effort in terms of proximity to the desired value for each dependent variable in the profile.
EnableHomotopy	If true, the profile will divide the problem into steps to solve it.
EnableLineSearch	If true, the profile will perform a line search.
HomotopySteps	Gets or sets the number of steps to divide a problem into for a homotopic calculation. Dimensionless - .
LineSearchLowerBound	Gets or sets the low boundary for the line search. Dimensionless.
LineSearchTolerance	Gets or sets the tolerance for the line search. Dimensionless.
LineSearchUpperBound	Gets or sets the high boundary for the line search. Dimensionless.
MaxIterations	Gets or sets the number of complete iterations of the profile to try before stopping. Dimensionless.
MaxLineSearchIterations	Gets or sets the number of line search iterations to try before stopping. Dimensionless.
NumIterations	Get the number of iterations of the last run.
Results	Get the list of results defined for the profile.
RootFindingAlgorithm	Gets or sets the root-finding algorithm to use.
ScriptingTool	Returns the Scripting tool for the sequence.
StopOnLimitCycleDetection	If true, Astrogator will stop targeting if a limit cycle is detected.
TargeterGraphs	Graphs.

Example

Configure target sequence with Differential Corrector profile

[C#]

IAgVAMCSTargetSequence startTransfer = driver.MainSequence["Start Transfer"] as IAgVAMCSTargetSequence;

string dcString = "Differential Corrector";

if (Array.IndexOf(startTransfer.Profiles.AvailableProfiles, dcString) != -1)
{
    IAgVAProfileDifferentialCorrector dc = startTransfer.Profiles.Add(dcString) as IAgVAProfileDifferentialCorrector;

    // Configure differential corrector
    dc.ClearCorrectionsBeforeRun = true;
    dc.ConvergenceCriteria = AgEVAConvergenceCriteria.eVAConvervenceCriteriaEitherEqualityConstraintsOrControlParams;
    dc.EnableBPlaneNominal = false;
    dc.EnableBPlanePerturbations = false;
    dc.EnableDisplayStatus = true;
    dc.EnableHomotopy = true;
    dc.HomotopySteps = 2;
    dc.EnableHomotopy = false;
    dc.EnableLineSearch = true;
    dc.LineSearchLowerBound = 0.001;
    dc.LineSearchTolerance = 0.001;
    dc.LineSearchUpperBound = 5.0;
    dc.MaxLineSearchIterations = 5;
    dc.MaxIterations = 20;

    // Apply
    startTransfer.ApplyProfiles();
}

Configure target sequence with Differential Corrector profile

[Visual Basic .NET]

Dim startTransfer As IAgVAMCSTargetSequence = TryCast(driver.MainSequence("Start Transfer"), IAgVAMCSTargetSequence)

Dim dcString As String = "Differential Corrector"

If Array.IndexOf(startTransfer.Profiles.AvailableProfiles, dcString) <> -1 Then
	Dim dc As IAgVAProfileDifferentialCorrector = TryCast(startTransfer.Profiles.Add(dcString), IAgVAProfileDifferentialCorrector)

	' Configure differential corrector
	dc.ClearCorrectionsBeforeRun = True
	dc.ConvergenceCriteria = AgEVAConvergenceCriteria.eVAConvervenceCriteriaEitherEqualityConstraintsOrControlParams
	dc.EnableBPlaneNominal = False
	dc.EnableBPlanePerturbations = False
	dc.EnableDisplayStatus = True
	dc.EnableHomotopy = True
	dc.HomotopySteps = 2
	dc.EnableHomotopy = False
	dc.EnableLineSearch = True
	dc.LineSearchLowerBound = 0.001
	dc.LineSearchTolerance = 0.001
	dc.LineSearchUpperBound = 5
	dc.MaxLineSearchIterations = 5
	dc.MaxIterations = 20

	' Apply
	startTransfer.ApplyProfiles()
End If
