  Window observers for linear systems

  摘要：

  Given a linear system (x) over dot = Ax + Bu with output y = Cx and a window function omega>(*) over bar * (t), i.e., For Allt, omega>(*) over bar * (t) is an element of {0,1}, and assuming that the window function is Lebesgue measurable, we refer to the following observer, (x) over cap = A (x) over cap + Bu + omega>(*) over bar * (t)LC(x - (x) over cap) as a window observer. The stability issue is treated in this paper. It is proven that for linear time-invariant systems, the window observer can be stabilized by an appropriate design under a very mild condition on the window functions, albeit for linear time-varying system, some regularity of the window functions is required to achieve observer designs with the asymptotic stability. The corresponding design methods are developed. An example is included to illustrate the possible applications.

  A mild and convenient protocol for the oxidative cleavage of 1,3-diketone compounds is described. Under metal-free conditions, the method converts the 1,3-dicarbonyls into amides when treated with (nBu4N)N3 and iodine in the presence of an amine at room temperature. Using this method, a range of 1,3-dicarbonyls with various structural motifs including sterically demanding substituents and ordinary

  A halogen resistant polyamide is formed from the reaction product of an amine monomer and an acid chloride monomer wherein the amino group of the starting amine monomer is separated from the aromatic amine ring system by an alkyl group and (i) minimizes halogenation on the amine and (ii) minimizes N-halogenation at a pH range of approximately 7 to approximately 10.5. A membrane is made from the polyamide for use, for example, in a reverse osmosis desalination unit.
