SystemsModelControllerData

SystemsModelControllerData[]

represents controller data generated by functions LQGRegulator, PIDTune, etc.

Details

  • A SystemsModelControllerData[] object cd can be used to retrieve data through cd["property"].
  • A list of available properties is given by cd["Properties"]. Additional details about the properties are listed on the page for each controller design function.
  • State feedback controller design functions include:
  • StateFeedbackGainspole placement
    LQRegulatorGainslinear quadratic (LQ) optimal control
    DiscreteLQRegulatorGainsapproximate discrete-time LQ optimal control
  • Output feedback controller design functions include:
  • EstimatorRegulatorassembling state feedback and state estimator
    LQGRegulatorLQ Gaussian optimal regulator and estimator
    PIDTuneautomatically tuned PID controller
  • Typical properties include:
  • "Design"type of controller design
    "ClosedLoopSystem"the closed-loop system with plant and controller
    "ClosedLoopPoles"the poles of the Taylor linearized closed-loop system
    "InputsCount"number of inputs
    "OutputsCount"number of outputs
  • Other specifications include:
  • {p1,,pn}get the values of properties pi
    "Dataset"get the property names and values as a Dataset
    "PropertyAssociation"get the property names and values as an Association
