SYSTEM AND METHOD FOR CONTROLLING OSCILLATORY INSTABILITIES IN A DEVICE |
| 摘要 |
A method for detecting onset of oscillatory instability in a device is described. The method includes obtaining a symbolic time series of a time series signal corresponding to a dynamic state variable of the device. The method further includes detecting the onset of oscillatory instability in the device based on the symbolic time series. |

1. A method for detecting an onset of oscillatory instability in a device, the method comprising:
performing analysis of a time series signal to detect onset of oscillatory instability, wherein said analysis is performed by considering that at said onset of oscillatory instability said time series signal exhibits specific patterns captured in a corresponding time window of said time series signal; generating a symbolic time series from said time series signal corresponding to a dynamic state variable of said device; identifying presence of oscillatory instability in said time series signal corresponding to said dynamic state variable by recognizing a change in said patterns; and detecting said onset of oscillatory instability in said device when occurrence of change in said patterns are recognized. |
