Accordingly, a zipper-fracturing mode was firstly adopted in the factory fracturing on wellpad.
The mathematical model for TCPST under different operation modes is firstly investigated in this study.
A reduced order state-space model which contains dominant low frequency oscillation modes is firstly identified online by using an closed-loop SMI algorithm.
To overcome this obstacle, the set of modes is firstly divided into two subsets standing for known transition rate subset and unknown one, based on which a state observer is established.
Therefore, a backstepping sliding mode approach is firstly applied, where the backstepping design is to synthesize the controller and the sliding mode term is to compensate disturbances.
In this work, the traditional method of sliding mode control is firstly modified for researching conveniently the synchronization tracking of uncertain discrete network.
However, in order to excite the surface modes, it is firstly needed to place a diffracting layer in front of the plasma layer to transform the incident propagating wave into evanescent wave.
A robust mode-dependent estimator is firstly designed to estimate the system states with the intermittent observations.
In view of the low frequency, low damping ratio and long duration characteristics of the inter-area oscillation mode, the stable region is firstly extended by the eigenvalue shifted factor in this paper.
The study of the physical properties of the polymer optical fibers (core diameter, numerical aperture, differential mode delays, modal bandwidth…) is firstly performed in order to effectively exhibit the potentialities and the robustness of such fibers to be used in a low cost radio over fiber system.
