Detailed Description

Performs modal analysis of an extracted discrete-time state-space model.

The analysis uses the state matrix provided by MNAStateSpaceExtractor and maps discrete-time eigenvalues to continuous-time EMT eigenvalues with the trapezoidal-rule relation:

lambda = 2 / dt * (z - 1) / (z + 1)

getContinuousEigenvalues()

const CPS::VectorComp & DPsim::StateSpaceModalAnalysis::getContinuousEigenvalues ( ) const

inline

Continuous-time EMT eigenvalues reconstructed from discrete eigenvalues.

Definition at line 52 of file StateSpaceModalAnalysis.h.

getDiscreteEigenvalues()

const CPS::VectorComp & DPsim::StateSpaceModalAnalysis::getDiscreteEigenvalues ( ) const

inline

Eigenvalues of the extracted discrete-time state matrix in the selected analysis frame.

Definition at line 47 of file StateSpaceModalAnalysis.h.

setAnalysisFrame()

void DPsim::StateSpaceModalAnalysis::setAnalysisFrame ( StateSpaceAnalysisFrame frame )

inline

Select the coordinate frame used for modal analysis.

Native uses the extracted EMT state matrix directly. GlobalDQ0 transforms registered abc state triples to a global dq0 frame.

Definition at line 30 of file StateSpaceModalAnalysis.h.

setGlobalDq0Frame()

void DPsim::StateSpaceModalAnalysis::setGlobalDq0Frame ( Real omega, Real theta0 = 0.0 )

inline

Set the global dq0 frame.

omega is the constant synchronous angular speed. theta0 is the global frame angle at t = 0.

Definition at line 38 of file StateSpaceModalAnalysis.h.

update()

void DPsim::StateSpaceModalAnalysis::update

(

)

Update modal quantities from the current extracted state matrix.
