Linearize airframe model around operating points
linearizes an airframe model around a specified operating point or operating point
specification object and generates an output state-space model that contains only
longitudinal states. A Linearize Airframe dialog window prompts you to
select an operating point or operating point specification object from the base workspace.
If an operating point or operating point specification object does not exist in the base
workspace, click the Launch Trim Tool button in the Linearize
Airframe dialog window. This button starts the Simulink®
Control Design™ Model Linearizer in which you can create the operating point specification
linSys = linearizeAirframe(
linearizeAirframe function uses this object as the
operating condition around which to linearize the airframe model.
Linearize the model
the operating point,
opTrim. This example starts the flight control
analysis template using
asbFlightControlAnalysis and trims the model
opSpecDefault operating point specification object. It then
linearizes the airframe model around the
opTrim operating point and
calculates the short- and long-period (phugoid) mode characteristics of
asbFlightControlAnalysis('3DOF', 'SkyHoggAnalysisModel'); opSpecDefault = SkyHogg3DOFOpSpec('SkyHoggAnalysisModel'); opTrim = trimAirframe('SkyHoggAnalysisModel', opSpecDefault); linSys = linearizeAirframe('SkyHoggAnalysisModel', opTrim) flyingQual = computeLongitudinalFlyingQualities('SkyHoggAnalysisModel', linSys)
modelToAnalyze— Model on which to perform flight control analysis
Model on which to perform flight control analysis. This model must be previously
created with the
opPoint— Operating point object
Operating point object used to linearize the model
generatePlots— Display pole-zero map
Display pole-zero map for the linear system state-space model.
linSys— State-space model object
State space model object representing the linearized airframe model at a specified operating point.
