Existence of a State Feedback of not Changing the Observability of the System

By modern cybernetics, we can find out a state feedback for a linear time system, which does not change the controllability and stability of the system. But whether a state feedback for linear time system can be found out, which does ont change observability of the system or not, so far hasn't been discussed. The problem is studied according to the steady discrete time linear system, and a state feedback is found out, which does ont change the controllability, observability and stability, by relation of stability, observability and characteristic root, rank of matrix, of steady discrete time linear system; the method of how to construct the state feedback is given.

Design of the BMS in the Automobile Insurance

During the research on automobile prize and punishment system, a novel method is proposed in terms of grouping by the history to claim the record, the ages of drivers and the types of the vehicle. When the factors are considered, the related data can be classified by homogeneity of risks and applied to design the prize and punishment system. Experimental results show that a more reasonable and fair system is obtained by using the above method.     

The compensation method for the random time-delay of the feedbackchannel and the forward channel in the networked control system

An improved predictive control method is presented to compensate the random time delay in the networked control system. The feedback time delay is compensated by predictive controller based on softened increment input strategy. The forward time delay is unknown for controller, so an extra feedback loop is added to compensate the delay by estimating the error between the actual control signal effected on plant and the output of controller in historical moment. For the controlled system with unknown or slowly varying parameters, the networked feedback correction algorithm is discussed based on a modified recursive least-squares identi cation algorithm. The system stability is analyzed and the simulation results show that the time delay in the networked control system can be accurately compensated. The excellent network performance is ensured with this strategy.

Influence of MUD on the System Capability of CDMA

In CDMA communication system, the relativities between users result in Multiple Access Interference (MAI). With the increase of users, MAI becomes the main jam of broadband CDMA communication system. Multi-User Detection (MUD) is the most important technology of anti-jamming in the broadband CDMA communication system, which can eliminates MAI effectively by using the information of all user signals to detection single. This paper analyze the expression of system capability without MUD and with MUD, and puts forward the way to increase system capability by using MUD. Then the influence of MUD on CDMA system capability is discussed by MATLAB emulation. Basing analysis and emulation, the conclusion is got: the higher the MUD efficiency, the better the improvement of CDMA system capability; under the same MUD efficiency, the lower data rate, the smaller inter-cell interference, the lower the ratio of bit energy to power spectrum, the better the improvement of CDMA system capability.

Experimental Research on the Application of Enviromental Protection Refrigerants in the Large-scale Screw-Refrigerator

On the research of alternative refrigerants, because of their advantageous thermal characters and unparalleled prepondrance of environmental protection, kinds of HCs substance have taken more and more scholars attention. At the base of full demonstration, the HCs is applied on large-scale screw-refrigerator for the first time. The result indicate that, although the autlwrs do not make any better about the system, the energy-efficiency-ratio(EER) of R290 system is equally matched R22 system. So R290 can alternate R22 in the refrigerant system and can works well. If some improvements are maken on the system against the flammability of HCs, then the large-scale refrigerant system with HCs as the refrigerant could march to the markets, and make immense social and economic benefits.
