Predictive control is actually widely used for industrial process control. A big number of points in the predictive horizon and control horizon are often chosen not only to ensure the quality of the dynamic process for slow processes but also to get a better robustness for the control system. But it will raise the computational effort of the controller. Blocking and coincidence points technology can reduce the computation time while keeping the length of the horizon, which consider a reduced number of points in the predictive horizon (coincidence points) as well as in the control horizon (blocking point). Base on step response, a new method of selecting coincidence points is proposed in this paper. The simulation results show that this method could not only achieve the objective of simplifying the calculation, but also have certain advantages in the fast performance and stability. Also, this method is simpler and more practical.

This paper deals with the problem of delay-dependent robust stability for systems with time-varying structured uncertainties and multiple time-varying state delays. Based on Lyapunov stability theory combined with linear matrix inequality technique, the new improved criteria are much less conservative and more general. Numerical examples suggest that the results are effective and are an improvement over previous ones.

It is necessary to evaluate the operational capability of the weapon equipment based on combat-simulation, however, the simulation data is so isomerous that it is difficult to make evaluation model. Pointing to this problem, a comprehensive method based on the TOPSIS, AHP and SIMULATION method (T-A-S) is built to evaluate the operational capability of weapon equipment. An example about the operational capability on armored equipment based on the T-A-S method is given, and the evaluation results can help to analyze the weapon combating performance. The results show the comprehensive method very feasible.

Batch verification signature is an efficient signature to generate and verify signatures for a batch of message in a single protocol. In the paper, analyses were made on the basic principles of batch verification signature, as to the security problems of present batch verification signature schemes; we presented an improved batch verification signature scheme based on HCC (hyper-elliptic curves cryptosystem). The scheme is composed of interactive protocol and non-interactive protocol for different application. As for security analyzing, we presented two cryptanalysis schemes against batch verification signature based on discrete logarithm cryptosystems. In the attack schemes, the signature generator can forge valid signature without his identity information, thus avoids identity tracing in signature verifying. Further detailed analyses have also justified the schemes' brevity, security, high efficiency, thus the signature schemes are more applicable to such circumstances as with restricted computation ability and integrated space, circumstances with limited bandwidth yet requiring for high-speed operation.

In this paper, the generalized asymptotic synchronization between Chen hyperchaotic system and Liu hyperchaotic system is investigated. The two hyperchaotic systems to be synchronized are represented by the T-S fuzzy models with a small number of fuzzy IF-THEN rules exactly. Then, based on the T-S fuzzy hyperchaotic systems, a simple fuzzy controllers is designed via parallel distributed compensation (PDC) and exact linearization (EL) techniques to realize the generalized asymptotic synchronization of the above two hyperchaotic systems. Simulation results are presented to demonstrate the validity of the proposed hyperchaotic generalized synchronization method.

With the economic globalization, networking, rapid development of IT and customization of customer requirements, supply chains must adaptively respond to its dynamic environment and customer requirements in order to keep long-term survival in a rigorous competition world. Traditional supply chains must change to adaptive supply networks (ASN). It is significant to study thoroughly the conception, characters and enabling technologies of ASN in current competitive market environment. ASNs have gained focus of both academic and practice areas. This paper gives a brief survey on ASN including definition, properties, research status and future trend.

In this paper, a novel blind source separation method based on the array-averaged Fractional Fourier Transform is proposed. This method can decrease the noise levels, and suppress the interactions of the source signals, which lead to better separation performance. Compared with the previous blind source separation techniques based on the time-frequency distributions, this proposed method produces little crossterms, and it does not require whitening, joint-diagonalization, and bilinear signal synthesis. The improved efficiency of the method is verified by the simulation.

Gas sensor array is an important part of electronic nose. The gas analysis performance of electronic nose is affected badly by the cross sensitivity of gas sensor array. In order to solve the problem of the cross sensitivity, in this work a new method based on support vector machine (SVM) is used for pattern analysis of gas mixture quantitative analysis. The proposed method has been used for processing the measuring data obtained by a gas mixture experiment of butane and ethanol, in which the sensor array is composed of three sensors. The results clearly show that the SVM is effective technique for gas mixture quantitative analysis. Also, the SVM can achieve better prediction accuracy than BP neural network.
