First, a descriptor system approach (DSA) is used to transform the normal system to a descriptor-system-form model equivalently. Based on descriptor systems' theory, new necessary and sufficient conditions of H_∞ control and α—stability for LTI systems are obtained.
Based on the expression of solutions to a normal system and Gronwall's inequality, the problem of variable structure control for singular uncertain system without matching condition is studied in view of the structure propeties of a singular system.
The nonstrict LMIs for the controller are transformed into strict ones by means of the matrix decomposition. So we may get the solutions directly to the problems via the LMI toolbox like the normal system case.
Further more the parameter design method of the saturated transformer type SSFCL is proposed, which reduces the coupling transformer and the DC reactor design capacity and does not affects the normal system operating and short-circuit limiting effect. The normal operation,satisfactory short current limiting results are also confirmed by the software simulations.
Let S(P) be a P-inversive semigroup. In this paper we describe the regular P-congruences on S(P) in terms of their P-kernel normal systerm. We prove that any regular P-congruence on S(P) can present a P-kernel normal system.
The paper expatiates economic effect and energy saving effect of ice storage system as cold source of air conditioning through the analysis of the daily thermal load curve of Shanghai metro station and the comparison of operation costs between ice storage system and normal system. And the advantages,control strategy and equip- ment confJguratJon of Jce storage system are introduced.
according to the rotation characteristic of rate bias platform, considering the scale errors of inertial instrument and the influence of rate bias platform, extending the normal system error equations, derives its system error equations and achieves initial alignment with kalman filter method;
Points out th at at the same thickness of heat insul ation,the temperature increase of the duct in l ow-temperature system is more than t hat in the normal system,and that wil l cause much fluctuation to lower air-supply tem perature.
The themes of this article are, in an enterprise of new economy, what the basic characteristics are, what problems should be paid attention to in accounting, financial, and audit control, how to strcngthen the culture construction of internal control, and how to establish the normal system of internal control.

The author point out that optional policies include:Perfecting the management of company,formulating a normal system of scientific nacessaty andhigh quality,strenthening supervision,and cultivating reasonal investors,etc.
Factorization of linear groups and groups which have a normal system with linear factors
In the last case it is shown that the problem of the extension reduces to the solution of a normal system of ordinary differential equations.
Here we show that a second transporter, System XAG-, is required for normal System xC-activity and glutathione maintenance by employing somatic cell mutants of CHO-K1.
We identify conditions which give rise to bistability, and propose a call admission control scheme which prevents the system from getting trapped in a congested-type equilibrium, while not interfering with normal system operation.
With the help of this prescription the particle-holeT-matrix approximation to the normal system is generalized by taking into account that in the superfluid state the spin fluctuations are propagated also by pairs of anomalous Green's functions.
