Class PlantSimulatorInitializer

Namespace

TimeSeriesAnalysis.Dynamic

Assembly

TimeSeriesAnalysis.dll

Intializes a plant simulator in the first data point

Currently, only initalizing to steady-state is supported.

By design choice, this class traverses the models by logic to initialize the plant model rather than using mathematical programming/matrix solvers.

Constructor

public PlantSimulatorInitializer(PlantSimulator simulator)

Parameters

simulator PlantSimulator

simulator object that already includes connections,models and signals to be simulated

Methods

EstimateDisturbances(TimeSeriesDataSet, ref TimeSeriesDataSet)

for a given inputData, compute every disturbance of every loop where U and Y are given

public int EstimateDisturbances(TimeSeriesDataSet inputData, ref TimeSeriesDataSet simData)

Parameters

inputData TimeSeriesDataSet

simData TimeSeriesDataSet

estimated disturbances are added here.

Returns

int

the number of estimated disturbances

EstimateDisturbancesAndPruneInputDataAheadOfSimulation(ref TimeSeriesDataSet, ref TimeSeriesDataSet, ref Dictionary<string, double>)

For a plant, go through and find each plant/pid-controller and attempt to estimate the disturbance. For the disturbance to be estimateable,the inputs "u_meas" and the outputs "y_meas" for each "process" in each pid-process loop needs to be given in inputData. The estimated disturbance signal is added to simData

public int EstimateDisturbancesAndPruneInputDataAheadOfSimulation(ref TimeSeriesDataSet inputData, ref TimeSeriesDataSet simData, ref Dictionary<string, double> signalValuesAtT0)

Parameters

inputData TimeSeriesDataSet

note that for closed loop systems u and y signals are removed(these are used to estimate disturbance, removing them triggers code in PlantSimulator to re-estimate them)

simData TimeSeriesDataSet

signalValuesAtT0 Dictionary<string, double>

Returns

int

returns the number of estimated disturbances

ToSteadyStateAndEstimateDisturbances(ref TimeSeriesDataSet, ref TimeSeriesDataSet, Dictionary<string, List<string>>, bool)

Initialize the empty datasets to their steady-state values

public bool ToSteadyStateAndEstimateDisturbances(ref TimeSeriesDataSet inputData, ref TimeSeriesDataSet simData, Dictionary<string, List<string>> compLoopDict, bool doEstimateDisturbances)

Parameters

inputData TimeSeriesDataSet

non-simulated time-series external inputs

simData TimeSeriesDataSet

simulation dataset containing only the external signals. The new simulated variables are added to this variable with initial values.

compLoopDict Dictionary<string, List<string>>

dictionary of all computational loops

doEstimateDisturbances bool

Returns

bool
