Tunable model of closed-loop transfer function between specified linearization I/Os
T = getIOTransfer(ST,input,output)
T = getIOTransfer(ST,input,output,openings)
T = getIOTransfer(ST)
T = getIOTransfer(ST,input,output) returns the linearized closed-loop response of the control system described by the slTunable interface ST. The response T is a genss model of the response from inputs input to outputs output.
T = getIOTransfer(ST,input,output,openings) computes T with feedback loops opened at the locations specified by openings.
T = getIOTransfer(ST) returns the response from all inputs to all outputs. This syntax is equivalent to setting inputs and outputs to the union of the IOs, Controls, and Measurements properties of ST.
ST |
slTunable interface describing a Simulink model. |
inputs |
String or cell array of strings specifying the signals that are inputs to the closed-loop response. Each signal in inputs must be present in the IOs, Controls, or Measurements properties of ST. For signals in ST.IOs, only signals of type in, inout, or outin can be used in inputs. The getIOTransfer command treats a signal in Controls or Measurements as a disturbance signal entering at the specified location. You can specify an abbreviated signal path in inputs provided the string matches the end of the full signal path and unambiguously identifies the signal. Default: 0-by-1 cell array |
outputs |
String or cell array of strings specifying the signals that are outputs of the closed-loop response. Each signal in outputs must be present in the IOs, Controls, or Measurements properties of the slTunable interface ST. For signals in ST.IOs, only signals of type out, inout, or outin can be used in outputs. You can specify an abbreviated signal path in outputs provided the string matches the end of the full signal path and unambiguously identifies the signal. Default: 0-by-1 cell array |
openings |
String or cell array of strings specifying the locations at which feedback loops are opened for the computation of T. Specify the locations as the names of signals listed in the Controls, Measurements, or Switches properties of ST. Loop openings listed in the Openings property of ST are always open. You can specify an abbreviated signal path in openings provided the string matches the end of the full signal path and unambiguously identifies the signal. Default: 0-by-1 cell array |
T |
Tunable genss model of the response from inputs input to outputs output. If input and output are omitted, T is the response from all inputs to all outputs listed in the IOs, Controls, and Measurements properties of ST. T captures the dependence of the response on the parameters of the tunable blocks in the TunedBlocks property of ST. The current values of the tunable parameters of T are equal to the current parameter values in ST. Therefore, you can use getIOTransfer after tuning ST with slTunable.looptune to examine closed-loop responses of the tuned control system. |
