摘要:

This paper presents a decentralized observation scheme for linear time‐invariant interconnected systems where the interaction is characterized by the subsystem outputs. Using the conventional optimal technique guaranteeing a prescribed degree of stability, the nominal observer gains are first calculated with respect to the decoupled system and then are multiplied by appropriate factors to adapt the interaction among the subsystems. This subsystem‐based approach not only can yield at least a prescribed convergent rate of the global reconstruction error system but also can effectively reduce the burden of computations and simplify the design procedures. Computer simulations of an example of a sixth‐order interconnected system containing three subsystems are conducted.

摘要:

Diamond crystals have been successfully synthesized on (100) Si wafer using microwave plasma CVD. The growth was conditioned in a flowing system in which the parameters, such as CH4/H2ratio, pressure, temperature and microwave power were varied. Cubo‐octahedra or tetrakaidecahedra are the equilibrium shape of diamond single crystals obtained under all conditions and are therefore the basic unit for the formation of polycrystalline diamond films, mostly through repetitive twinning and secondary growth of diamond crystals on {100} habit planes of cubo‐octahedra. Both X‐ray diffraction and Raman spectroscopy were used to facilitate the analysis of the diamond crystallinity and purity. These qualities are similar to those of natural diamonds.
