Dissipative Control of the State Delayed Systems

1　 IntroductionSince the notion of dissipative system was introduced by Willems ( 1 972 a) [1 ] ,andsubsequently generalized by Hill and Moylan( 1 980 ) [2 ] ,it has played an important role insystems,circuits,and control.Dissipativeness is a generalization of the concept ofpassivity in electrical network and otherdynamical systems which dissipate energy in someabstract sense.Applications of dissipativeness in the stability analysis of linear systemswith certain nonlinear feedback were first…

On Fixed Points of Linguistic Dynamic Systems

1 Introduction1 Humans employ mostly words in computing and reasoning arriving at conclusions expressed as words from premises expressed in a natural language. When we deal with a special type of dynamic system that modeled by 搘ords? we use the theory of linguistic dynamic systems (LDS) by Wang[17, 18]. This is true especially when we deal with social or economic, rather than engineering or physical systems. For many large complex systems, however, due to the complexity involved and the in…     

Status and Perspectives of Process Systems Engineering

The definitions, methodology, applications, and perspectives of process systems engineering are discussed from a strategic point of view. The focal points in future development of process systems engineering are to break through in methodology, to expand application fields, and to develop a new generation of process simulation systems.     

Information Measures of Roughness of Knowledge and Rough Sets for Incomplete Information Systems

1 IntroductionRough set thcory, introduced by Pawlak [lj, is a relatively new soft computing tool todeal with vagueness and uncertainty. It has been applied to many areas successfullylncluding machine learning, data analysis, pattern recognition, decision support, datamining, process control and predictive modeling [1--6j.Rough set theory gives a formal definition of knowlcdge and provides a series of toolsto deal with know1cdge by set a1gebra. In rough set theory, know1edge can be regarded a…

Application of Neurocomputing in Adaptive Control of Large-Scale Aerospace Systems

We are engaged in solving two difficult problems in adaptive control of the large-scale time-variant aerospace system. One is parameter identification of time-variant continuous-time state-space modei; the other is how to solve algebraic Riccati equation (ARE) of large order efficiently. In our approach, two neural networks are employed to independently solve both the system identification problem and the ARE associated with the optimal control problem. Thus the identification and the control computation are combined in closed-loop, adaptive, real-time control system . The advantage of this approach is that the neural networks converge to their solutions very quickly and simultaneously.
