Syntax

linSys = linearizeAirframe(modelToAnalyze)
linSys = linearizeAirframe(modelToAnalyze)
linSys = linearizeAirframe(modelToAnalyze,opPoint)
linSys = linearizeAirframe(modelToAnalyze,opPoint,generatePlots)

Description

example

linSys= linearizeAirframe(modelToAnalyze)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. ALinearize Airframedialog 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 theLaunch Trim Toolbutton in theLinearize Airframedialog window. This button starts the金宝app®Control Design™Model Linearizer in which you can create the operating point specification object. ThelinearizeAirframefunction uses this object as the operating condition around which to linearize the airframe model.

linSys= linearizeAirframe(modelToAnalyze)linearizes an airframe model around the specified operating point object or operating point specification object.

linSys= linearizeAirframe(modelToAnalyze,opPoint)linearizes an airframe model around the specified operating point object or operating point specification object.

linSys= linearizeAirframe(modelToAnalyze,opPoint,generatePlots)displays bode and step plot results of longitudinal linearization.

Examples

Linearize the modelSkyHoggAnalysisModelaround the operating point,opTrim. This example starts the flight control analysis template usingasbFlightControlAnalysisand trims the model around theopSpecDefaultoperating point specification object. It then linearizes the airframe model around theopTrimoperating point and calculates the short- and long-period (phugoid) mode characteristics oflinSys.

asbFlightControlAnalysis('3DOF','SkyHoggAnalysisModel'); opSpecDefault = SkyHogg3DOFOpSpec('SkyHoggAnalysisModel'); opTrim = trimAirframe('SkyHoggAnalysisModel', opSpecDefault); linSys = linearizeAirframe('SkyHoggAnalysisModel', opTrim) flyingQual = computeLongitudinalFlyingQualities('SkyHoggAnalysisModel', linSys)

Input Arguments
