基于可拓论的工业水分过程系统综合建模

介绍了工业水分过程系统建模的研究方法。该文采用数学机理模型、经验模型、神经网络模型在物元模型的基础上综合方法，建立了大时延、大流量、大范围非线性时变的烟丝水分过程的模型。该模型以数学机理模型的解作为初始点，经验模型作为全局调节器，菱形思维神经网络模型作为局部调节器，从而使该模型更接近于实际工业过程。此方法物理机理明晰、能获得工业过程的全局优化结果、能解决系统中一些结构不良问题等。仿真结果表明：较之三种模型的有效性，对于解决复杂工业过程控制系统问题，可知工程方法是一条可探索途径。

Non-Minimum Phase Nonlinear System Predictive Control Based on Local Recurrent Neural Networks

Abstract: After a recursive multi-step-ahead predictor for nonlinear systems based on local recurrent neural networks isintroduced, an intelligent PID controller is adopted to correct the errors including identified model errors and accumulatederrors produced in the recursive process. Characterized by predictive control, this method can achieve a good controlaccuracy and has good robustness. A simulation study shows that this control algorithm is very effective.     

IS γα≤δ FOR GRAPHS WHICH HAVE DIAMETER TWO?

A subset of S of the vertex set of a graph G is called acyclic if the subgraph it induces in G contains no cycles. S is called an acyclic dominating set of G if it. is both acyclic and dominating. The minimum cardinality of an acyclic dominating set, denoted by 7a(G), is called the acyclic domination number of G. S. M. Hedetniemi et al. on 2000 introduced the concept of acyclic domination and posed the following open problem: Is -ya(G) < <5(G) for any graph whose diameter is two? In this paper, we give a counterexample which disproves the problem.     

Dynamic Characteristics of Inter-Satellite Links in LEO Networks

To establish an efficient inter-satellite link (ISL) in an LEO network, the effect of geometric characteristics of ISL on the ISLs and the devices on the LEO satellite should be examined. Because of the continuous movement of the LEO satellite, the time-varying behaviours of the ISL's geometric charactersistics continuously change with the changes of the satellite's position on the orbit. These dynamic geometric characteristics of the ISLs are important for ISL's performance analyzing and the design of the devices on the LEO satellite. This paper describes dynamic geometric characteristics of ISL, analyzes the impact of these regulations on the tracking system of the satellite's antenna and the power adjusting system of the satellite's transmitter, with the Iridium system as an example.
