The state feedback decentralized fuzzy controller is considered in this paper. Based on Lyapunov criterion and Razumikhin theorem, some sufficient conditions are derived to stabilize the whole perturbed fuzzy time-delay system asymptotically. Moreover, if all the interconnection matrices A/sub ij//sup l/ and time-delays /spl tau//sub ij//sup l/(t) of each subsystem are the same for all rules, we shall propose a simpler and less conservative criterion. These criteria do not need the solution of a Lyapunov equation or Riccati equation. The so-called \"matching condition\" for the interconnection matrices and perturbations are not needed.","PeriodicalId":212172,"journal":{"name":"The 12th IEEE International Conference on Fuzzy Systems, 2003.

This approach can be applied to control the lateral directional dynamics of the missiles at high angle of attack or generate moments on missile operating in flight regimes where the effectiveness of conventional aerodynamic surfaces is reduced. Using an adaptive fuzzy approximation method, the uncertain nonlinear model of the missile system is estimated. Then, by a mixed H/sub 2//H/sub /spl infin// control design, the effects of external disturbance and fuzzy approximation error as well as consumed energy of the controller is minimized. By the skew symmetric property of the missile system and adequate choice of state variable transformation, this problem can be reduced to solve two algebraic Riccati-like equations. Furthermore, a closed-form solution to these two algebraic equations can be obtained with very simple form for the preceding control design.","PeriodicalId":212172,"journal":{"name":"The 12th IEEE International Conference on Fuzzy Systems, 2003.

Fuzzy models - when obtained from system measurements - represent good example of such approaches. Because the emphasis is on its accuracy, the obtained model may exhibit unnecessary complexity which hampers its transparency and computational cost. This paper deals with the issues of transparency and accuracy of data-driven fuzzy models. We present an automated method to simplify data-driven fuzzy models. This method targets simplifying rather than reducing the model. However, model reduction may follow from its simplification if it contains high redundancy.","PeriodicalId":212172,"journal":{"name":"The 12th IEEE International Conference on Fuzzy Systems, 2003.

The traditional pulse compression algorithms based on 13-element Barker code such as direct autocorrelation filter (ACF), least squares (LS) inverse filter, and linear programming (LP) filter have been developed, and the neural network algorithms were issued recently. However, the traditional algorithms cannot achieve the requirement of high signal-to-sidelobe ratio, and the normal neural network such as backpropagation (BP) network usually produces the extra problems of low convergence speed and sensitive to the Doppler frequency shift. To overcome these defects, a new approach using a neural fuzzy network with binary phase code to deal with pulse compression in a radar system is presented in this paper. The 13-element Barker code used as the binary phase signal code is carried out by six-layer self-constructing neural fuzzy network (SONFIN) with supervised learning algorithm. Simulation results show that this neural fuzzy network pulse compression (NFNPC) algorithm has the significant advantages in noise rejection performance, range resolution ability and Doppler tolerance, which are superior to the traditional and BP algorithms, and has faster convergence speed than BP algorithm.","PeriodicalId":212172,"journal":{"name":"The 12th IEEE International Conference on Fuzzy Systems, 2003.

One is the idea of being provided with queries inside which preferences are used instead of classical Boolean conditions. Basically, such queries are addressed to regular databases and any element of the result is associated with a d e m e of satisfaction used to rank-order the answers. On the other hand, one may face a situation where some pieces of information are not known precisely (automated recognition of objects in images, data fusion, linguistic descriptions, ..., etc). This leads to store and query a new type of data with respect to that dealt with in commercial systems. When fuzzy sets (indeed possibility dis~butions) are used to model such data, one gets fuzzy databases. Obviously, flexible queries can also be used against fuzzy databases, but the two issues are fundamentally independent.","PeriodicalId":212172,"journal":{"name":"The 12th IEEE International Conference on Fuzzy Systems, 2003.

When the process contains a long dead-time, prediction using linear derivative control will not work because the measured signal will not contain sufficient information about any future changes that may occur in the loop. Under these conditions, the anticipatory nature of the derivative controller fails to ensure proper control of deadtime dominant processes. This paper proposes a fuzzy logic tuned, polynomial based nonlinear predictor to improve the control of plants experiencing instability due to long dead-times. The proposed predictor replaces the derivative controller in a PID controller, and contributes towards a general improvement of the control performance in systems having long dead-times.","PeriodicalId":212172,"journal":{"name":"The 12th IEEE International Conference on Fuzzy Systems, 2003.
