| Research Abstract |
This research develops a system identification device for control system's design. A prototype of the hardware has been developed and a GUI (Graphical User Interface)that supports system identification operation has been installed in the system identification device. The system identification device also includes new system identification methods such as
1) System identification method based on SVM (support vector machine),
2) System identification methods for non-uniform sampling data.
The former method that is SVM-based system identification method is proposed for linear regression models such as ARX (Auto-Regressive with eXtra input) model, and it is shown that the method is robust for input-output data with outliner.
In the latter method, non-uniform sampling data is first transformed to uniform sampling data whose sampling period is smaller than the original data. Second a system identification method with missing data estimation is applied to the data.
The effectiveness of the developed system identification device is examined using experimental apparatus such as an inverted pendulum and an active noise control svstem.
