도움말 항목
- Specify Estimation and Validation Data in the App
You should use different data sets to estimate and validate your model for best validation results.
- Select Subsets of Data
Select portions of data for identification in the app or at the command line.
- Create Data Sets from a Subset of Signal Channels
You can create a new data set in the System Identification app by extracting subsets of input and output channels from an existing data set.
- Create Multiexperiment Data Sets in the App
You can create a time-domain or frequency-domain data set in the System Identification app that includes several experiments.
- Create Multiexperiment Data at the Command Line
You can create
iddata
objects that contain several experiments. - 다중 실험 데이터 및 모델 병합 처리하기
이 예제에서는 System Identification Toolbox™를 사용하여 모델을 추정하고 미세 조정할 때 다중 실험 및 모델 병합을 처리하는 방법을 보여줍니다.
