A Structured Methodology for Local Network Design Engineering

This paper presents a structured methodology for local network design engineering (SMLNDE). A complex and fuzzy project for local network design can be decomposed into a set of simple and particular activities using the SMLNDE. The SMLNDE allows rigorous requirements definition and permits the exhaustive consideration of the large number of factors influencing local network design engineering. The complete and clear design documentations and an optimal design can also be provided by the methodology. The SMLNDE has been implemented using the structured analysis and design technique. The study shows that the SMLNDE is an effective design methodology for the large and complex local networks.

Design of unknown input observer with H_∞ performance for linear time-delay systems

1 .INTRODUCTIONThe dynamic behavior of many physical processes ,such as chemical process , long transmission lineand rolling mill systems , contain ti me-delay anduncertainties . Ti me-delay usually results in unsat-isfactory performance andis frequently a source ofinstability , so control of ti me-delay systems ispractically i mportant , especially state feedbackcontrol . A unknown input observer has i mportantapplications in realization of state feedback con-trol . An UIO is an esti ma…

A New Method with High Confidence for Validation of Computer Simulation Models of Flight Systems

Computer simulation models may by used to gain further information about missile performance variability. Model validation is an important aspect of the test program for a missile system. Validation provides a basis for confidence in the model's results and is a necessary step if the model is to be used to draw inference about the behavior of the real missile. This paper is a review of methods useful for validation of computer simulation models of missile systems and provides a new method with high degree of confidence for validation of computer simulation models of missile systems. Some examples of the use of the new method in validating computer simulation models are given.
