Robust Absolute Stability of General Interval Lur''''e Type Nonlinear Control Systems

1. INTanDUCTIONIt is wellknown that the absolute stability problem for Lur'e type noIilinear control systems has been studiedby many researchers (NarendIa and Taylor 1993, Zhao 1993, Xiong 1995, Haddad 1995, Park 1998). Grujic andPetkovski (1987) and Tsypkin et al. (1993) gave robust circle criterion and robust popov criterion for absolutestability of Lur'e system. Tesi aJnd Vicino (1991), Dahleh, et al.

AN INTELLIGENT CONTROL SYSTEM BASED ONRECURRENT NEURAL FUZZY NETWORK AND ITS APPLICATION TO CSTR

In this paper, an intelligent control system based on recurrent neural fuzzy network is presented for complex, uncertain and nonlinear processes, in which a recurrent neural fuzzy network is used as controller (RNFNC) to control a process adaptively and a recurrent neural network based on recursive predictive error algorithm (RNNM) is utilized to estimate the gradient information ρy/ρu for optimizing the parameters of controller.Compared with many neural fuzzy control systems, it uses recurrent neural network to realize the fuzzy controller. Moreover, recursive predictive error algorithm (RPE) is im-plemented to construct RNNM on line. Lastly, in order to evaluate the performance of the proposed control system, the presented control system is applied to continuously stirred tank reactor (CSTR). Simulation comparisons, based on control effect and output error,with general fuzzy controller and feed-forward neural fuzzy network controller (FNFNC),are conducted. In addition, the rates of convergence of RNNM respectively using RPE algorithm and gradient learning algorithm are also compared. The results show that the proposed control system is better for controlling uncertain and nonlinear processes.     

ESTIMATION METHOD FOR SOLUTIONS TO GENERAL LINEAR SYSTEM OF VOLTERRA INTEGRAL INEQUALITIES INVOLVING ITERATED INTEGRAL FUNCTIONALS

1. IntroductionThe study of Volterra-type integral inequalities had aroused much research illterest on thepart number of authors. In recent years, various VOlterra inequalities involving iterated illtegralfunctionals have also been investigated. We refer to 11--14] for related results for such inequalitiesin one independent variable. However, there is no result reported in the literature which isconcerned with arbitrary finite systems consisting of such integral inequalities. Obviously suchk…     

Theoretical Computation of Nonlinear System Equations of Heavier Pellets Movements for Two Phase Flow

This paper presents nonlinear ordinary differential equations (ODES) of the heavier pellets movement for two phase flow, which actually represent a system of equations. The usual methods of solution such as Runge -Kutta method and it's datum results are discussed. This paper solves ODES of general form using variable mesh-length, linearizing the nonlinear terms by finite analysis method, fuilding an iteration sequence, and amending the nonlinear terms by iteration . The conditions of convergent operation of iteration solution is checked. The movement orbit and velocity of the pellets are calculated. Analysis of research results and it's application examples are illustrated.

A FRAMEWORK OF FUZZY LANDSCAOE THEORY WITH AN APPLICATION TO ALLIANCE ANALYSIS

In this paper,we provide a framework of fuzzy landscape theory and discuss an application to alliance analysis.The fuzzy landscape theory may allow us to analyses a variety of aggregation processes in political,economic,and social problems in a more flexible manner.The simulation 3results for the problems of the international alignment of the Second World War in Europe and the coalition formation in standard-setting alliances in the case of the UNIX operation system are compared with those given by the original theory.
