Research on the Disturbance Observer Based Generalized Wind/Solar Intergration Control Strategy
Zhongguo dianli, 2020 With the high proportion of distributed renewable energy sources, such as photovoltaic and wind power, connected to the micro-grid, the uncertainty of its power generation output brings significant pressure to the safe and stable operation of the micro ...

Multi-cyclone analysis and machine learning model implications of cyclone effects on forests
International Journal of Applied Earth Observations and Geoinformation, 2021 Past studies of cyclones (hurricanes, typhoons, tropical cyclones) disturbance showed that meteorological, topographical, and biological factors affect the patterns of forest disturbance intensity but left open the extent to which these findings were ...

Journal of Low Frequency Noise, Vibration and Active Control, 2021 Vibrations are usually caused by continuous disturbances with large amplitudes. Different from other control methods, disturbance rejection control is a potential method, which considers the unknown disturbances in the control design.

The Conal representation of Quantum States and Non Trace-Preserving Quantum Operations [PDF]
, 2002 We represent generalized density matrices of a $d$-complex dimensional quantum system as a subcone of a real pointed cone of revolution in $\mathbb{R}^{d^2}$, or indeed a Minkowskian cone in $\mathbb{E}^{1,d^2-1}$.
